hello, can I ask if you'd need to know examples for genetic counselling? (e.g. sickle-cell anaemia is detected, and how genetic counsellors would advice)? thanks :)
Hi! The specification says "The use of labelled DNA probes and DNA hybridisation to locate specific alleles of genes" , so you need to know how DNA hybridises for AQA. Also, there have been lots of exam questions in the past asking how you would you hybridisation to measure how closely related two organisms / DNA sequences. Probes bind to the complementary sequence by DNA hybridisation too :)
