If they were gonna ask about covid measures in a 6 marker or 4 idk was just thinking, what would you guys talk about? do pcr and the DNA stuff have something to do with it in terms of the swabbing and perhaps bioinformatics ??

Depends what the question is asking because it could be a 6 marker in cloning and biotech but then again, it could be a 6 marker on diseases.
Also: for the swabbing part - you could probably refer to that fact that they use monoclonal antibodies to identify if you have covid or not - same thing applies to pregnancy tests.

hox genes are regulatory genes that control body development in animals through mitosis and apoptosis(programmed cell death).

Haven't watched the other two, but biorach is defenitely great, she's very good at laying out the info in an easy to understand way

Am I the only one felt the Diversity paper is soo hard and makes no sense.

Even though I’ve done quite well in paper 1, I’m so scared that I’m going to fail paper 2 and get really low grade.

The mark schemes are just so SPECIFIC and saying random sh*t we haven’t learnt.

Why do we even care plants or diversity? I think it’s so pointless and waste of time. (My personal opinion)
