    hopefully!!
    i really want the structure of the heart to come up but it's not really 6 marker quality if that makes sense,
    has anyone got access to the 2014 paper?

    I would hate for the structure of the heart to come up as a 6-marker. I'd be really grateful for a negative feedback homeostasis one, though

    B7 is the best unit ah love it! I'm predicting a lot on the new technologies section as there was only like tick box stuff on last years paper. Probably some stuff on the heart, insulin levels and muscles.

    the gene responsible for vitamin a is first isolated and the copies are made.the gene is then joined to a vector such as a plasmid which is then transferred into a new cells.something like that.hoped it helped.

    Vector = molecule that carries DNA information and inserts that into other cells

    Isolation = isolating the gene in the daffodil that produces vitamin A (which was transferred to the rice using the vector)

    Transferred = Gene is transferred to rice

    The scientist used a gene probe to identify and isolate the gene in the daffodil that was responsible for Vitamin A production. S/he then used a florescent marker to identify the probe's position, and extracted it. The scientist then transferred this Vitamin A-producing gene to the rice using vectors (like plasmids), which carry DNA information.

    I can only find one past paper on the OCR website.... The 2013 June one
    Is there a reason for why there were no papers before this?

    woooo only 4 more exams til my exams are over & 3 of them are science (yay, not, lol!)

    i'm looking forward to P and B7 but not C7 i suck at that.

    B7 - i think muscles and like the joints will come up as a 6mq (i bloody well hope not tho)
    - maybe gm crops??
    - and maybe closed loop and perfect loop ecosystems??

    also how did you guys find physics yday? i bluffed p5 but p6 and p4 were quite nice. when i saw iggy the cat i instantly thought iggy azalea and started giggling wtf.
