Try three 2.7 Application of Reproduction and Genetics exam-style questions
1. State the role of DNA ligase in genetic engineering. (1 mark)
Show the mark scheme answer
It joins the sugar-phosphate backbones of DNA fragments.
2. Explain one limitation of gene therapy. (2 marks)
Show the mark scheme answer
The effect may be temporary (1) as treated cells die and must be replaced, requiring repeated treatment (1).
3. Explain how PCR amplifies DNA. (3 marks)
Show the mark scheme answer
DNA is heated to separate strands (1); primers anneal on cooling (1); DNA polymerase extends the strands, and cycles repeat (1).
