The idea
To discuss importance, you must present more than one side and reach a judgement. Understanding the human genome matters scientifically because it shows how genes work and how humans compare with other species. Medically, it supports predicting disease risk, selecting treatments, developing medicines and understanding inherited conditions. Socially, it raises questions about privacy, consent, insurance and fair access. A strong answer names a benefit, explains the mechanism, gives a concern, and weighs them. For example, knowing a variant raises the risk of a condition could allow earlier monitoring, but the same information could lead to discrimination if shared. Use connectives such as 'however' and 'therefore' to build the discussion, and finish with a clear overall view.
What earns the marks
- Identify several areas of importance, such as medicine, understanding inheritance, and comparing species.
- Explain how genome knowledge produces a specific benefit, for example identifying risk variants or targeting treatments.
- Present concerns, such as privacy of genetic data, consent, cost, or possible discrimination.
- Weigh benefits against concerns and reach a justified overall judgement.
- Use accurate terminology, including genome, genetic variant, inherited disorder and personalised medicine.
Common mistakes and how to put them right
Writing a one-sided list of benefits.
Put it right by adding concerns and a balanced conclusion.
Giving vague importance such as 'it helps doctors'.
Put it right by naming a specific use and explaining how the genome sequence enables it.
Confusing discussion with description.
Put it right by comparing points and stating which arguments are stronger and why.
Exam tips
- Plan two columns, benefits and concerns, then write a conclusion that follows from your points.
- Use the word 'because' to link each point to its consequence, showing reasoning rather than assertion.
- Keep ethical points specific, such as insurance discrimination or data privacy, instead of general worries.
