    can somebody please explain to me the grade boundaries for last year then? I thought it was 80% as an A in which case, I just got an A last year, if it's lower I'm a comfortable A... Will they be the same this year? :/

    The question "which drug is not similar to dopamine structurally" was a bit thought-provoking however, as they all at least bound to one thing which dopamine did, suggesting a similar structure. I went for the MAO repressing one.

    Thoughts, anyone?

    Wasnt that bad, believed i did well. Although i messed up species diversity/evenness as i wasnt paying attention by that point. I thought i did pretty well, i could be penalised one or two areas for being vague.

    I put rotational coppicing and selective felling of trees as the 2 techniques, and prevention of soil erosion and diverse range of habitats maintained.

    Hopefully i get my B or Above that i want.
    ....and now i have to revise chemistry after this break :P

    I put rotational coppicing, and increases biodiversity provides more habitats etc but after i kinda thought.....that isnt really being precise about how it makes timber sustainable? Worried me now.

    i put it'd break down the (sucrose was it?) to glucose providing a respiratory substrate for culture bacteriaa

    yeah, as it could be a non-competititve inhibitor which would bind to the allosteric site which wouldnt have same shape as dopamine

    80% UMS is always an A. But you may need less than 80% raw marks to get 80% UMS. E.g last June you needed 66/100 to get 120/150.

    I didn't right anything about 'apoptosis inhibitors', don't even know what they were :P I wrote the main bulk of the question about the formation of the proteins, then a little bit of blah on different functions of proteins like enzymes, hormones, combination with glycogen for cell surface receptors etc... then I wrote about the different homeobox genes- maternal-effect, segmentation and homeotic selector

    Not sure if thats right at all :eek3:
    i wrote a paragraph explaining how polypeptides are made.

    then i talked about how homeotic genes have regions called homeobox sequences that code for homeodomain, and that its works as the transicription factor , how when its attached to developmental genes its activates of represses transcription of polypeptides involved in the development of the body plan etc

    Yeah I chose that one too, because it could be a non-competitive inhibitor (theory from AS) which means it does not bind to the active site but can still change the shape of the MAO so it cannot function

    EDIT: I CANT ACTUALLY REMEMBER WHICH ONE I WENT FOR AHHA BUT THAT WAS THE THEORY BEHIND IT

    it was the phenelsomething. The one that wouldn't bind to the receptor as the receptor is complementary to the shape of dopamine

    I think I put that one. I talked about how it would inhibit the enzyme in a non-competitive manner.

    I couldn't figure out the genetic cross - should have understood that more thoroughly before the exam :rolleyes: Apart from that, most of it went quite well- I hope

    same here i said it would be complementary but not identical, that was a nasty question though

    Oh yeah that question! We were supposed to talk about transcription and translation for the first part right? That took up a lot of space.

    that's complicated :/

    I always worked out that you multiplied whatever you got in the exam by 1.5 to give you your ums marks... so last year I got 65, 118 and 56 in the course work which is 239/300 which is 80% but that might not be an A? :confused:

    O.O So crazy it might just be right, I put kill harmful bacteria and prevent contamination/spoliage.

    But it could be a competitive inhibitor and therefore has a similar structure to Dopamine.
