    yep you know it!!
    Remember that to make proteins, DNA is converted into messenger (m)RNA as DNA is too large to leave the nucleus. The mRNA acts as instructions for the ribosomes, which produce the protein.

    RNA polymerase makes the mRNA from the DNA.
    Thanx although that's not what hes referring to apparently.

    What is the extension of PCR?

    I was referring to the extension stage of PCR...
    Haven't got a clue, looks like it's back to the revision guide.

    Extension of PCR is when Taq DNA polymerase copies the DNA after the primers have annealed. 72ºC....

    PCR is the polymerase chain reaction.
    if we want to copy some DNA, we heat it to 95 degrees to separate the strands. Cool it to 55 to allow the primer to anneal. Then heat it to 72 degrees to allow Taq Polymerase to bring free nucleotides and allow the new strand of DNA to be formed.


    My advice would be to forget the past papers and focus on revising the specifics from the revision guide. I am willing to bet that this paper will be heavily focussed on just relaying information rather than exam technique focussed questions.

    cool, might start doing that as doing past papers seems a bit pointless, it's not like they ask the same questions each year :\

    i find that for bio theres no point in doing past papers cos its better to perfect your knowledge so you can apply it cos all papers this year are applied

    I would say briefly go over the wishy washy chapters like ecosystems, as a lot of it is common sense. Definitely go over genetics! It's such a big chapter there is bound to be multiple questions on it. I'm going through past papers and looking up the questions/topics I really get stuck on, good luck!!!
    Thanks!!! Will do and good luck to you too!!!
