    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
    i wrote about this..

    i missed electrophoresis then ran out of time so just put 'Please see plan'

    my teacher was saying if we write about 3 things in considerable detail then we should be ok...

    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.
    May not be over but you will have to pay an extra £6000 a year!

    Exam was terrible :/ there were so many little topics which i had been over but not bothered about too much and concentrated on the big stuff like impulses nerves muscles etc. And what comes up? The frikkin one line worth of topic in revision guides!!! Damn AQA! :mad: im so worried and upset now and really demotivated for chem..what a waste of revision :/ i did cycles essay, i wrote about resp, PS, carbon and nitrogen cycle..i mentiomed about insulin and glucose but didnt know whether that was a cycle so wrote it briefly and now regret not writing more! Hope the cycles are enough though otherwise fail I couldnt think of anything to do with AS and so wrote a quick paragraph on water into plants. Didnt have time so mentioned transpiration and predator pray cycle in my plan, hopefully theyll mark that too...Also, i wrote about haemoglobin and how it associates and dissociates O2, will that count as cycle? And in the essay could we write CO2 rather than carbon dioxide? Thanks

    if i dont get into uni this year my life may aswell be over
    Why? You may have to pay higher tuition fees etc etc but so will thousands of others.
    Not denying it's retarded but people will cope.

    O I did...
    Gene therapy, fingerprinting, probes, electrophoresis + blot
    Filled up all the pages. Could have written SO much more if I had more time.

    They may want you to specify, because both DNA and RNA have pentose sugars.

    What did people write for the movement of IAA? That was weird...and another thing that was weird was the question that said: Why is transcriptional factors important? What a broad question, that could have anything for an answer but it was only 2 marks?

    What did everyone put?

    Oh yeah it was like by which process does IAA move to other cells of the plant or something? I put diffusion :\ the word process made me think it was a one word answer
