    I chose 5:2
    You get plantlets and leaves. Evidence from the table showed that leaves could develop into full plantlets (from callus of course).

    Which is better?
    To get plantlets and then having to cut leaves or getting plantlets and some leaves so that new plantlets can form?
    But wasn't there 2 plantlets and leaves ones? One being 50:5 and one being 25:10 from what I remember, so how are you to decide which of those 2 is best? To me the fact that plantlets were the only one that was alone in the box suggested that was what they were after. Who's the say when it says Plantlets it doesn't mean 10, and Plantlets and leaves could mean 5 Plantlets 5 leaves, I'd rather have 10 plantlets .

    But yeah I get what you're saying, just to me there wasn't enough info there and my knowledge of growing papaya plants isn't great, so 5:1 seemed the most logical to me.

    Shrug, 2 marks

    I did the DNA essay, there was so much to write about it so couldn't write about anything in so much detail. It was mostly unit 5 though, a bit of unit 2.

    There was a lot of content, but just worded to make you apply the content rather than recite it! I think it was a decent exam, and since this is only the second exam on this specification, not many people knew what to expect!

    YES

    I had it in my plan but didn't have enough time to stick it down.

    The only redeeming thing about that paper is that the cycles essay was the ONLY ONE I PRACTICED, and I got 23/25 for it. I almost squee'd with happiness when I saw it. Dohohohoho :awesome:

    Love how everyone immediately goes "oh no how science works! I've failed and therefore my life is over forever!!"

    Chill out people, it wasnt that HSWy and grade boundaries will be low I'm sure. Anyway even if you don't get into uni this year you life is not over.

    yeh i did. but i wonder if i did enough
    i wrote about-
    DNA probing and sequencing etc in id for mutated gene
    Genetic fingerprinting
    DNA hybridisation- in the AS spec with measuring relationship with DNA between two samples
    Gene therapy
    Modifying DNA for crop animals and medicine..

    Do you think I've done enough for breadth? What did you write?
    I wrote about probing, electropheresis and fingerprinting - cloning in vivo and in vitro (so PCR restriction endonucleases, reverse transcriptase, vectors etc.)

    didnt pick anything up from AS stuff but i think i wrote plenty anyway

    For the electrophoresis question, did any1 put fragments seperate due to differences in size and they can predict how large they by comparing them with known size fragments along side ??

    No, but we do have to pay 3 times the price if we apply next year.

    He-LLOOO Clearingg!

    Pissed. Missed more questions than I ever have before (went back and wrote rubbish in them after)
    Possibly the worst biology exam I've done. Learnt entire book before exam literally only skipped a bit of the menstrual cycle because it was too confusing and i ran out of revision time. What comes up? I put that Oestrogen stimulates follicle growth FML.

    The endonuclease/mapping thing was a joke. The rest was all practically HSW which I blatantlyy got wrong. What dideveryone put for the lizard?

    I actually liked the second to last question on enzymes for phosphate/lactase and krebs cycle though. Nice 4 marker. What did everyone put for the second question? It was mathematic, to do with complimentary bases? I put 16 and 17. and also the question after that.. what was it again?

    no definition questions!

    Oh and the process by which growth factors (or something) reach their target cells I put Diffusion? and there was another question about how they reach target cells.. i put through blood/ bing to receptors on cell surface membranes.
