Matched to a verified specialist who knows your course, your university's marking criteria, and your deadline.
Topics we cover
FLN offers one-to-one online Molecular Biology tutoring with verified subject specialists. Sessions focus on core theory, clinical application and exam preparation, including DNA Structure and Replication, RNA Structure and Function, Gene Expression and Transcription, using your own course material, so you understand the subject and can apply it yourself.

Molecular biology help is one-to-one support from a molecular biologist who explains how genetic information is stored, copied and expressed, and helps with lab techniques, calculations and reports.
| What you need | Best option | What you get |
|---|---|---|
| Regular lessons through a molecular biology module | Live one-to-one tutoring | Mechanisms explained step by step |
| Calculations or problems you are stuck on | Homework help | Worked solutions |
| A graded lab report | Assignment help and lab report help | Guidance within your rules |
This map lists the core molecular biology topics, the point where students most often get stuck, and how a tutor helps you past it.
| Topic | Where students get stuck | How a tutor helps |
|---|---|---|
| DNA structure | Base pairing and antiparallel strands | Labelled structure diagrams |
| Replication | Enzymes and leading and lagging strands | Process flow diagrams |
| Transcription | RNA polymerase and processing | Worked transcription examples |
| Translation | The genetic code and ribosomes | Worked codon reading |
| Gene regulation | Operons and eukaryotic control | Regulation diagrams |
| PCR | Cycles, primers and Tm | Worked PCR calculations |
| Electrophoresis | Reading gels and fragment sizes | Gel interpretation practice |
| Cloning and CRISPR | Vectors, restriction enzymes and editing | Workflow diagrams |
Tutors cover school and university syllabi.
| Area | Topics |
|---|---|
| Nucleic acids | DNA and RNA structure, chromatin, genome organisation |
| Information flow | Replication, transcription, RNA processing, translation |
| Regulation | lac and trp operons, transcription factors, epigenetics, RNAi |
| Mutation | Mutation types, DNA repair |
| Techniques | PCR, qPCR, electrophoresis, blotting, sequencing |
| Recombinant DNA | Restriction enzymes, vectors, cloning, expression |
| Genome editing | CRISPR–Cas9, applications and ethics |
Three common lab calculations.
| Question | Working | Answer |
|---|---|---|
| 100 template copies after 30 ideal PCR cycles | 100 × 2³⁰ | ≈ 1.07 × 10¹¹ copies |
| Melting temperature of a 20-base primer with 10 G or C (Wallace rule) | Tm = 4 × (G + C) + 2 × (A + T) = 4 × 10 + 2 × 10 | 60 °C |
| dsDNA with A260 = 0.5 after a 1 in 10 dilution | 0.5 × 50 µg/mL × 10 | 250 µg/mL |
The Wallace rule is a quick estimate for short primers; online calculators give more accurate Tm values.
A DNA template strand reads 3′-TAC GGA TTC ACT-5′.
| Step | Sequence | Notes |
|---|---|---|
| mRNA (complementary, 5′ to 3′) | 5′-AUG CCU AAG UGA-3′ | U replaces T |
| Codon 1 | AUG | Methionine (start) |
| Codon 2 | CCU | Proline |
| Codon 3 | AAG | Lysine |
| Codon 4 | UGA | Stop |
| Polypeptide | Met–Pro–Lys | Three amino acids |
A single base change in codon 3 from AAG to UAG would create an early stop codon: a nonsense mutation.
Tutors match your level, syllabus and exam board, from school to PhD.
| Level | What you study | Matching help |
|---|---|---|
| A-Level and IB | DNA, protein synthesis and gene technology | A-Level AQA Biology, IB Biology SL |
| CBSE Class 12 and NEET | Molecular basis of inheritance and biotechnology | CBSE Class 11 Biology and live tutoring |
| BSc and biomedical science | Molecular biology modules and labs | Bioinformatics, homework help |
| MSc and PhD | Molecular research projects | Assignment help and dissertation help |
Related: Genetics, Cell Biology, Biochemistry and Biotechnology.
Most lost marks come from strand direction errors and vague technique descriptions.
| Mark-loser | What to do instead |
|---|---|
| Ignoring 5′ and 3′ ends | Label strand directions at every step |
| Reading the template as the mRNA | Write the complementary mRNA first |
| T used in RNA | Replace T with U in RNA |
| PCR steps without temperatures | Give denaturation, annealing and extension conditions |
| Gel bands misread | Compare with the ladder and remember small fragments run further |
| No controls in lab reports | Describe positive and negative controls |
Molecular biology is assessed in several formats, and each one is marked on different things. Tutors help you understand the brief and the marking criteria before you start.
| Assessment | What markers look for |
|---|---|
| Exams | Mechanisms, problems and data interpretation |
| Lab reports | Methods, gels, calculations and discussion |
| Data questions | Interpreting gels, sequences and qPCR results |
| Essays | Explaining molecular processes with evidence |
| Projects | Molecular cloning or analysis projects |
Molecular biologists use these tools.
| Tool | What it is used for |
|---|---|
| Thermal cyclers | PCR |
| Gel electrophoresis kits | Separating DNA fragments |
| Spectrophotometers such as NanoDrop | Quantifying DNA and RNA |
| NCBI BLAST and primer design tools | Sequence analysis |
| SnapGene or Benchling | Plasmid maps and cloning design |
Molecular biology is taught to similar core ideas worldwide, but grading, referencing and course structure differ. FLN tutors work from your own syllabus and handbook and schedule lessons in your time zone. Always follow your module handbook for referencing.
| Country | Where molecular biology is studied | Grading | Referencing usually used |
|---|---|---|---|
| United Kingdom | A-Level Biology and BSc biology and biomedical science | GCSE 9–1, A-level A*–E; degrees First, 2:1, 2:2, Third | Harvard or a journal style |
| United States | AP Biology and college molecular biology | Letter grades A–F and a 4.0 GPA scale | APA, CSE or ACS |
| Australia | Biology and biomedical degrees | HD, D, C, P at university; ATAR for school leavers | Harvard or APA |
| Canada | Biology and biochemistry programmes | Letter grades or percentages; GPA scales vary by province and university | APA or CSE |
| India | CBSE Class 12, NEET, and BSc and MSc life sciences and biotechnology | Board exam percentages; university CGPA, often on a 10-point scale | As your university specifies |
Students in Ireland, the Gulf, Europe, Africa and Asia can book the same help, with lessons in their own time zone.
The price of molecular biology help depends on the type of task and your deadline. A short calculation costs less than a full lab report. You always see the price first: a fixed quote for homework and assignment guidance, or the tutor's hourly rate for live lessons, with no contract and no minimum number of sessions. Refunds follow our refund policy.
