How to answer A-level Biology essay questions
The Synoptic essay questions in paper 3 of the AQA A-level biology course carries 25 marks, so can make a big difference to your overall grade. The essay encourages you to think across different topics (some call this “synoptic” or “holistic” thinking). This is also valuable for other areas of the exams, particularly the application questions .
Here are a few tips for tackling your A-level biology essay: (As an example, Let’s use the title “The importance of movement in cells and tissues”)
Think broadly…
Essay titles are deliberately vague to give you the chance to show your knowledge in a variety of topics. To help you to choose what’s most relevant, look out for subjective words like “movement” and “cells”. Think of the possible alternatives. “Cells”, for example, hints that you could discuss plants, animals, single-celled organisms etc. in your essay. “Movement” could mean short distances (across a membrane) or much further (circulation or mass flow) or even the whole tissue moving (phototropism).
Visualize and catastrophize!
If you can’t think of enough topics for an “importance” essay, flip the question around – what would happen if movement in cells suddenly ground to a halt? Or if ATP suddenly vanished, or our cells were robbed of their ions? Sometimes catastrophizing in this way frees up thoughts, and helps you see what is really important. Another way is to picture every diagram in your notes or textbook that features the thing-that’s-important-in-the-question. If it’s in a diagram, it could go in your essay.
Pick your strongest topics
It’s possible to drop marks on the essay for scientific errors. With that in mind, even if you have lots of ideas for things to include, always pick the topics you can write confidently about. For bonus marks, try to order them in a way that “flows” like a story. Take care to use A-level (and not GCSE) language too.
Keep an eye on the question
While you’re writing, keep asking yourself “Where am I placing the emphasis?”. If the essay is about movement, perhaps you don’t need a whole page about nervous responses, only the bits where movement is involved – sodium ions flowing through channels, waves of depolarisation etc. Movement is the focus of the essay, after all, not neurons. Always ask yourself “Does this sentence fit with the title of the essay?”
Use outside knowledge
The top marks for the essay are reserved for displaying “evidence of reading beyond specification requirements”. Often you can drop recent scientific research or news into your writing – how vaccines tackle COVID might work in an essay about viruses, for example. I often encourage students to have a quick look at the news pages of New Scientist pages (eg https://www.newscientist.com/subject/health/ ) before paper 3 for inspiration – you don’t need to spend ages doing this, just long enough to have one or two ideas up your sleeve…
Good luck with your essay!

How did you do?
Suggest the mechanism by which the defensive enzymes destroy bacterial pathogens (lines 9-10).
A stimuli can result in the expression of genes. Suggest how the signal proteins cause the expression of the defensive enzyme genes (lines 9-13).
Pepper plants can transmit signal proteins both into the air and also through mycorrhizal networks (lines 10–14). Suggest which method of signal protein transmission is more likely to be effective. Justify your answer.
In pepper plants, the largest increase in defensive enzyme secretion observed in response to the presence of the signal protein was 119.4 % (lines 19–20).
The rate of secretion of the defensive enzymes before the presence of signal protein was 500 µmol dm −3 g −1 hour −1 .
Calculate the rate of secretion per second after the response to the presence of signal protein.
_________________________ µmol dm −3 g −1 minute −1
A journalist who read the text above concluded that farmers should not be allowed to use fertilisers to increase the yield of pepper plants. Evaluate their conclusion.
Did this page help you?
Suggest why more than one person was used for the creation of the reference sequences (lines 11 - 16).
Describe how some base substitutions in the DNA sequence of a gene can be harmless while others can lead to disease through altered protein-protein interactions (lines 20 - 23).
The cancer cells within a particular patient were found to be caused by the known overexpression of a specific gene. Suggest and explain how a medical cancer treatment could be tailored to the individual (lines 29 - 33).
The sequencing machines can sequence 80,000 bases in 1 second. (lines 9 -11) If the human genome is 6,200 megabase pairs long, how much time will it take to sequence a whole human genome. 1 megabase pairs = 1,000,000 base pairs. Give your answer in hours.
Some of the patients with cancer exhibited zero differences or variation in their genomes from the reference genome. One of the researchers suggested that there could be important differences in their epigenomes. Explain what an epigenome is and suggest how epigenetic changes could cause cells to become cancerous.
Genome sequencing can be used to sequence the genomes of disease-causing viruses and bacteria. Suggest how the genomic information obtained about these organisms could be applied in human medicine.
Explain how genetic fingerprinting would allow scientists to identify the mother and father of an adolescent Amur leopard that had been released into the wild.
Explain why genetic variation within a wild population is important. Suggest how DNA fingerprints could be used to help maintain genetic variation within the captive Amur leopard population.
Explain why the primers used bind solely to Amur leopard DNA, and not to the DNA from other organisms present in the faeces (lines 13 - 16).
Blood or tissue samples can also be used to obtain DNA from Amur leopards. Suggest a disadvantage of using a blood or tissue sample to obtain DNA from Amur leopards.
12% of the population on the small island near New Zealand are affected by total colour blindness (lines 9–11)
Use the information provided to calculate how many more times an individual on the island is likely to have total colour blindness compared to an individual living elsewhere. Show your working.
Red-green colour blindness affects more men than women but blue-yellow colour blindness affects men and women equally (lines 12–13 and lines 16 -19). Explain why.
People with red-green and blue-yellow colour blindness are unable to distinguish between other colours as well. (lines 12–19). Explain why.
Some of the recent research into the treatment of red-green colour blindness involves the use of gene therapy (lines 20 - 25). Suggest how gene therapy cells could correct red-green colour blindness.
The use of induced pluripotent stem cells (iPS cells) could prove a more successful method than gene therapy for the correction of red-green colour blindness (lines 26–27). Using the information provided, suggest and explain two reasons why.
Two couples, couple X and couple Y , used a genetic screening service to find out if they were likely to pass on any harmful alleles to their potential children. The genomes of all four individuals were sequenced and any harmful mutations identified. None of the parents showed signs or symptoms of MD.
The results revealed the following:
- Couple X had a 25% probability of their children having
- Couple Y had a 100% probability of their children having
Using your knowledge of inheritance and the information in lines 6–10, explain the results of couple X and couple Y .
A small amount of DNA was extracted from the couples mitochondrial and nuclear DNA. PCR was carried out before sequencing.
Suggest how altering the anticodon of a tRNA results in MD (lines 10–13).
The post-exercise blood lactate concentration of an individual with MD is often much greater than the normal range (line 16). Suggest why.
