    EXACTLY! You just have to answer the rest of the question correctly for that stain!

    Did anyone do the Genetics q? How many loci were there? I said 8...

    I said 7 loci. There were 3 labelled ones and another 4 scattered out

    Were there not 7 chromosome pairs? And 8 loci, as there were 8 individual genes shown?

    A locus is the exact location on a gene on a chromosome.

    Yeah it was 8. There were 8 seperate genes, therefore 8 different positions or Loci.

    The independent is talking about a Genetic engineering question. I've suddenly very glad i did 5 q's, cos I totally missed that.
    Was it a part of the genetics question?? Cos I thought that was just the locus things and then natural selection?

    think it mita been 4 loci, alleles have the same positions on chromosomes.... who knows really..
    thought the paper was fine... just didnt realise it said scientistS for natural selection.. w/e!! its over!

    Yeah I dont know what they were looking for there, how many different loci or just how many loci.

    Didnt anyone else find some of the questions a bit vague?

    i think it was a answer to the parkinsons disease where they can use stem cells to replace the myelin sheath

    Hate to drag up an old thread but this bugging me...

    Did anyone do the ecology long question? And was it just me or was the experiment in that same question a wierd emalgamation of two of the ecology experiments. We never carried out a quantitative analysis on animals, just plants. What did anyone use for that? I used a quadrat to get spiders! lol

    And would it not be folded rather than globular for the enzyme, seein as they can be either globular or fibrous?

    i did the capture recapture method for the ecology question and i said it was folded, just because that was all i could think of on the day

    can they be fibrous? not sure... would they have an active site if they were?

    I did that too but I think I got the calculations wrong... It's so long since I've studied maths :p

    yeah, keratin and myosin are fibrous proteins

    but crap... that would appear to be 27 marks up the swanny for me

    there is a formula for the capture/recapture method. Can't remember it off the top of my head. Unless they gave you numbers, I doubt they wanted you to do calculations. maybe they wanted the formula though?

    i haven't looked at the paper yet

    As regards the loci, I was talking to a friend of my mother's, a biology teacher, she reckons they'll have to accept both 4 and 8, it's not exactly clearly y'see. So joy for all!


    Oh, and I did the capture recapture method and the quadrat as I wasn't totally sure I'd the formula right for capture recapture. Hurrah for two ways of doing things!

    Don't think there was. One question asked about the shape of the enzyme and that's what they're talking about methinks. :)

    The capture/recapture method is amoutn caught on first visit by amount caught on second visit over amount caught that were tagged on second visit. I made a MESS of that and did it the same as for plants (quadrat, line and belt), but just changed it to animals. **** :eek:
