Module 3: Model Essay
Read this sample essay written the way a strong C1 student writes, and see how the target pairings fit in.
It is often argued that scientists should be free to change the genes of an embryo if that stops a serious illness. I see the point, but I do not think the answer is a simple yes. The idea is highly attractive, yet the choice is deeply personal for families and for society, so I only partly agree.
A further consideration is that the benefit can be truly life-changing. A hereditary condition can follow a family for generations, and a therapeutic change to a single variant in the genome could end it. If the treatment passes careful clinical trials first, I find the aim wholly justified. A parent who has watched a child suffer would probably agree, because waiting for a natural cure can mean years of pain for that child.
Admittedly, there is a real risk of going too far. Editing the germline means the change is passed on to every later generation, and nobody can ask those people for permission. Once the door is open, choosing eye colour or height, which is simply enhancement, could follow. That path leads towards eugenics, which many people find utterly unacceptable. On this question society is deeply divided, and I understand why a choice about one single trait worries people.
On balance, I would allow this research only for serious diseases, with strict rules and independent checks. Using it for enhancement should stay strictly forbidden. That way we keep the benefits without losing public trust, which is absolutely essential for any new science. Doctors, researchers and ordinary citizens should all have a say in where the line is drawn.
