    What did people put for the mutation question and how it leads to a non functional protein.
    i described the types of mutation so deletion and substitution and told about how they work

    What did you guys write about why above 40% shouldn't be used?
    I said that if they used something above 40%, there's a chance that the clear zone will be so big that it may merge with the other zones, making the overall results unclear.

    That's more detail than what I wrote. I panicked on it since I don't remember seeing it in the textbook or the specification.



    That's what I wrote as well. How many marks was it? It was only 1 right?
    Yeh was a tricky question, was 2 worth marks though

    Yeah, did your invigilators not tell you? That's why the code on the paper had an 'R' on, they had to redo the paper for security reasons.

    it was because a college were given paper 2 instead of paper 1 so they knew everything on paper 2 thats why we were given a replacement c

    I thought this Paper 2 was a lot better than Paper 1 - probably because there was more time for revision.

    Surprisingly, there was a lot more on practical work and not much on the ventilation and heart.

    What did you guys write for question 2 about the exo and edo enzymes and why both of them working together is better.
    Think I got that one wrong
    so first endopep makes the long polypep chain into shorter chains and exposes more amino acids at the ends on the chains- therefore, more enzyme substrate complexes..I dont know how to explain it properly but if you think about it, a polypep as two 'ends' -if i cut it into two chains, i now have 4 'ends'
