University of Helsinki Genetics and Molecular Biosciences Master’s Thesis Guide 2026-2027

The Master’s Programme in Genetics and Molecular Biosciences (GMB) at the University of Helsinki is a 120 ECTS, two-year Master’s programme in the Faculty of Biological and Environmental Sciences. The programme is built around research in genetics, genomics, biochemistry, structural biology, cell and developmental biology, and molecular and physiological biosciences.

This guide is based on current University of Helsinki material verified on 26 August 2026. It focuses only on the 2026-2027 thesis process. Admissions, tuition fees, scholarships, application deadlines and language-test requirements are deliberately outside this article.

Four current study tracks

GMB currently has four standard study tracks:

• Biochemistry and Structural Biology;
• Genetics and Genomics;
• Cellular and Developmental Biology; and
• Molecular and Physiological Basis of Health.

The thesis should make sense within the student’s chosen academic direction, but GMB is deliberately interdisciplinary. Research questions can combine experimental and computational work, molecular mechanisms, omics data, cellular systems, structural methods or health-related molecular biology depending on the project and supervision arrangement.

A current structure-page discrepancy you should know about

Two current University programme pages presently describe the internal 120 ECTS allocation differently.

The dedicated Structure, content and study tracks page gives:

• 48 ECTS common studies;
• 57 ECTS study-track-specific studies; and
• 15 ECTS optional/free-choice studies.

The broader Studying page gives:

• 55 ECTS common studies;
• 50 ECTS study-track-specific studies; and
• 15 ECTS optional/free-choice studies.

Both total 120 ECTS, and both agree that the Master’s thesis is 30 ECTS. Because the two current public summaries conflict only on the common-versus-track-specific allocation, this guide does not silently choose one split and present it as universally authoritative.

For your own degree structure, use the current dedicated structure page, your active Sisu plan and programme guidance. The stable thesis facts are more important here: GMB is 120 ECTS, has four study tracks, and every student completes a 30 ECTS Master’s thesis.

The thesis is 30 ECTS and normally research-based

All GMB students complete a 30 ECTS Master’s thesis. The programme describes the normal thesis pathway as an experimental research project carried out in a University research group under the supervision of an experienced researcher.

The thesis is then written in the style of a scientific publication. That means the manuscript should not merely describe what happened in the laboratory or analysis pipeline. It should explain the research question, place the project in the existing literature, justify the methods, present the results clearly, discuss limitations and interpret what the findings mean in relation to previous knowledge.

A strong GMB thesis demonstrates:

• scientific thinking;
• familiarity with the research topic;
• command of relevant research methods;
• ability to plan and manage a research project;
• critical interpretation of evidence; and
• clear written scientific communication.

Even when the research is part of a larger project, the student’s own intellectual and practical contribution must remain identifiable.

Experimental work is the programme norm, but Faculty rules are broader

GMB’s own programme description strongly emphasises experimental research-group work. However, the current Faculty of Biological and Environmental Sciences rules also allow a Master’s thesis to be based solely on literature or other scientific source material when appropriate.

These two layers should not be confused.

For most GMB students, an experimental or data-driven thesis connected to a research group is the natural programme pathway. A literature-based thesis is possible under the Faculty framework, but it should be agreed through the programme’s thesis-planning and supervision process rather than assumed automatically.

Research-project courses can prepare you for thesis work

Current GMB instructions include research-project options such as:

• GMB-005 Research project, 10 ECTS; and
• GMB-008 Research project in biochemistry/structural biology, 10 ECTS.

These projects are useful because they expose students to the practical research cycle before the full 30 ECTS thesis: defining a question, working with methods or data, documenting procedures, handling unexpected results and communicating findings.

They are not substitutes for the Master’s thesis. Instead, they can help you test a research environment, develop technical skills and understand what kind of project is realistic within a Master’s timeframe.

Start planning through GMB-099 and your PSP

The current GMB personal study plan process begins in Sisu during GMB-099 Principles of Life, 10 ECTS. This is also when students receive early guidance on the programme and study-track selection.

Thesis planning should not be postponed until every other course has been completed. Current GMB guidance says thesis support becomes especially relevant when about half of the advanced studies have been completed.

At that stage, support can come from:

• the thesis instructor;
• teachers of the Master’s thesis seminar;
• the PSP teacher; and
• the responsible person for the student’s study track.

Current PSP guidance also identifies GMB-019 Master’s thesis seminar meetings across first-year spring and the second year. Use those meetings to narrow the research question, identify a supervisor, understand writing expectations and keep the project on schedule.

Viikki research environment

GMB is closely integrated with research at Viikki Campus. Current programme material highlights research infrastructure and expertise in areas including:

• genomics;
• proteomics;
• structural biology;
• biological imaging;
• genetics and gene regulation;
• cell and developmental biology; and
• molecular and physiological biosciences.

This matters for thesis planning because the feasibility of a project depends on more than the research question. You also need access to appropriate supervision, data or biological material, equipment, software, laboratory infrastructure and enough time to complete the work safely and reproducibly.

A technically impressive project that cannot be completed within the Master’s timeframe is a poor thesis plan. A narrower project with clear methods and interpretable results is usually stronger.

Faculty planning guidance: about 4-5 months and 20-40 pages

The current Faculty of Biological and Environmental Sciences framework describes the 30 ECTS Master’s thesis as approximately:

• one full-time term;
• 4-5 months of work;
• around 20-40 pages; and
• around 40-50 sources.

A literature-based thesis usually requires considerably more sources.

These figures are planning guidance, not rigid minimums or maximums. A thesis with extensive methods, figures, supplementary material, bioinformatic workflows or complex experimental results may be organised differently. The point is to keep the project analytical, focused and proportionate to 30 ECTS.

Do not pad the thesis to reach a page number. Equally, do not use a short manuscript to avoid explaining the scientific background, methodology, analysis and interpretation that the research question requires.

A separate thesis plan must be approved before the work proceeds

Current Faculty rules require a separate written thesis plan approved by the degree programme before the thesis work is carried out.

The supervision arrangement should make the following clear:

• research objectives and research question;
• how the research will be conducted;
• the supervisor or supervisors;
• the roles and responsibilities in supervision;
• the detailed timetable;
• thesis language and supervision duration; and
• handling of confidential data or results where relevant.

The plan also has a defined validity period. If it expires before submission, or the topic, supervisor or circumstances change materially, the plan must be updated or reapproved.

This is an important project-management safeguard. In experimental biosciences, delays can arise from sample availability, instrument access, failed experiments, data quality or analysis complexity. The plan should therefore contain a realistic project scope rather than the largest possible research question.

Supervisor qualifications and responsibilities

Under the current Faculty framework:

• the chief supervisor must hold a doctoral degree or equivalent qualification; and
• additional supervisors must hold at least a Master’s degree.

The supervisor can help with research design, methods, experimental strategy, data interpretation and scientific writing. The student remains primarily responsible for progressing the project, conducting the work, performing the analyses and writing the thesis.

If the project uses shared datasets, shared laboratory work or analyses produced by other researchers, document clearly what was done by you and what was contributed by others. Good scientific practice requires transparent attribution.

Ethics, data and reproducibility belong in the plan

GMB projects may involve biological samples, genetic or genomic information, health-related data, cell systems, animal material, bioinformatics or collaborative datasets. Depending on the project, ethical approval, data-protection requirements, material-transfer conditions or other permissions may apply.

Resolve these issues with the supervisor before collecting or accessing data when necessary. Do not assume they can be fixed at the writing stage.

For computational work, preserve enough information about software, versions, parameters, preprocessing and analysis decisions for the work to be understood and, where appropriate, reproduced. For laboratory work, maintain clear research records and follow the research group’s approved procedures.

Write it like a scientific article

Current GMB and Faculty guidance points toward a scientific-publication style. A typical structure may include:

1. introduction and scientific background;
2. research aims or questions;
3. materials and methods;
4. results;
5. discussion;
6. conclusions where appropriate; and
7. references and relevant appendices.

The exact structure should follow the current programme, Faculty and supervisor instructions for your project.

The verified public evidence does not establish one universal named GMB citation style such as APA, Harvard or Vancouver for every thesis. The Faculty requires a consistent referencing system and leaves detailed conventions to programme-specific guidance.

Use one system consistently and follow the current instructions provided for your thesis environment.

Thesis language

GMB is a multilingual programme. Current programme information says the thesis can be written in English, and students fluent in Finnish or Swedish can also use those languages where the applicable degree-language rules permit.

Do not decide thesis language only from convenience. Confirm the formal degree-language requirement in your Sisu plan and current University language instructions, especially if you are completing the degree in English.

Sisu and final E-thesis submission

Before final submission, follow the current University registration instructions in Sisu and submit the assessed thesis through the redesigned E-thesis system.

Once the final thesis has been stored for assessment, it is no longer editable.

Before submitting, verify:

• the correct final PDF;
• title and metadata;
• thesis language;
• abstract and keywords;
• supervisor information;
• references;
• figures, tables and supplementary material;
• accessibility where required;
• confidentiality boundaries; and
• that all contributions by other researchers are acknowledged.

Do not upload a draft expecting to replace it after the deadline.

Two examiners and supervisor independence

The responsible person appoints two examiners for a GMB thesis. Under the current Faculty rules, examiners normally hold a doctoral degree or equivalent qualification, and it is recommended that at least one examiner comes from the student’s Faculty or degree programme.

A crucial GMB rule is that the supervisor cannot act as an examiner. The Faculty has a specific justified exception for ECGS; that exception does not apply to GMB.

This separation is important because supervision and independent examination serve different functions.

Assessment areas and final grade

The current Faculty framework evaluates seven areas:

1. thesis objective and research questions;
2. scholarly framework and use of sources;
3. research data and method;
4. presentation of results;
5. discussion and conclusions;
6. thesis as an academic text; and
7. work during the thesis process.

The examiners assess areas 1-6, while the supervisor assesses area 7. The final thesis grade uses the 0-5 scale, and the Dean makes the formal approval and grading decision.

For a research-intensive programme like GMB, this means a technically difficult experiment does not compensate for an unclear research question or weak interpretation. Likewise, elegant writing does not compensate for poorly justified methods. The thesis is assessed as a scientific whole.

GMB uses a separate maturity test

GMB does not use the thesis abstract itself as the Master’s maturity test.

Current Faculty instructions list GMB among the programmes using a separate maturity test. After the thesis has been submitted to E-thesis, students can complete the maturity test in Examinarium by registering in Sisu for VIIKB-001 and selecting the implementation for GMB. Another arrangement can be agreed with the responsible thesis teacher.

If the thesis is your final remaining study before graduation, the maturity test must be completed before or on the same day as the thesis submission.

The maturity test:

• carries 0 ECTS;
• is assessed pass/fail;
• demonstrates familiarity with the field of the thesis; and
• has language requirements that depend on previous education and degree-language history.

AI is never allowed in a maturity test.

AI use in the thesis itself

University policy can permit AI-supported learning or writing where the relevant programme, Faculty, teacher and supervisor rules allow it. When AI use is permitted, follow any disclosure or reporting requirements and remain responsible for accuracy, references, data handling and research integrity.

Do not use AI to replace source reading, experimental judgment, statistical reasoning or scientific interpretation that you must be able to explain and defend yourself.

GMB thesis submission schedule for 2026-2027

The Faculty of Biological and Environmental Sciences uses the following current schedule. The completed thesis must be submitted by 23:59 Finnish time on the submission deadline.

There is normally no thesis supervision or feedback in July unless specifically required. Work backward from the Dean decision you need rather than assuming submission itself completes the process.

Public thesis and Helda

A Master’s thesis is a public document. Confidential information must not be placed inside the public assessed thesis. If the project is connected to unpublished research, patient-related material, a company or another restricted dataset, agree early what can appear in the thesis and what must remain outside the public document.

Current E-thesis and Helda rules govern archiving and publication. Plan confidentiality and publication before writing the final version, not after submission.

A practical GMB workflow

1. Use GMB-099 and your PSP to choose a realistic track direction.
2. Build methods experience. Research projects such as GMB-005 or GMB-008 can help you understand research-group work before the thesis.
3. Start thesis discussions around the middle of the advanced studies. Use GMB-019 seminar support and your PSP/thesis contacts.
4. Find a feasible research question and supervisor. Match the project to available data, laboratory resources, analysis capacity and the 30 ECTS timeframe.
5. Resolve ethics, permissions and data responsibilities. Do this before the relevant research starts.
6. Prepare and approve the thesis plan. Make the timetable and responsibilities explicit.
7. Conduct the project systematically. Keep records, document methods and distinguish your own work from collaborators’ contributions.
8. Write alongside the research. Do not postpone the literature, methods and figure preparation until the end.
9. Use 4-5 months and 20-40 pages as scope checks, not quotas.
10. Follow a consistent referencing system and current programme guidance.
11. Register correctly in Sisu and submit the exact final PDF through E-thesis.
12. Complete the separate VIIKB-001 maturity test. No AI is allowed in that test.
13. Allow time for examiner assessment and Dean approval.
