    Why is it diagonal.
    Because A on one strand must have the same % of T on the other, due to complimentary base pairing. Same for C and G.

    It was diagonal because the number had to match the base pair, right?

    dyu reckon I will lose a mark for not including the lymphatic system??... spoke purely about osmostic pressure at the venule end being greater than hydrostatic pressure which makes liquid move back into plasma by osmosis... I WAS SO TEMPTED TO JUST WRITE LYMPHATIC SYSTEM RIGHT AT THE END AS WELL! :P usually theres like 5 marking points and only 3 are required on questions like this so just wanted clarification

    Complementary base pairs. A bases in one strand must have the same number of T bases in the other strand.

    If you have an A on one strand, there'll be a T on the other strand.

    Hehe, me too.
    I remember last night I was imagining what it would feel like to get full marks...

    ...well I needn't have bothered, it isn't happening any time soon.
    I was pushed for time! I could have done with another 10 minutes to check my answers tbh.

    I'm not looking forward to results day

    im sure you'll have done fine.
    My friend had 3 exams today, and i think he's still doing an R.S one now.
    At least he did the RS one after the biology and not the other way round :P

    I did biology around 30mins after RS ( and i wrote like 15sides in rs) so all I could remember was keywords from that exam.

    Sigh, nothing I can do about it now tho...

    How did you find the DNA strand Q?

    Itsaid 148 base pairs(or something like that) so you had to double it to find the number of bases.

    Then A pairs with T
    And C pairs with G

    So there must be the same number of A and T.
    and C and G for each strand.
    Oh no I got it in the end it just took me ages

    The way I saw the DNA question was that if you imagined the 2 strands of DNA binded together, the number of Cytosines on the A strand equals the number of Guanines on the B strand. So it had to be diagonal otherwise it wouldnt make sense
