    Question 2 b)ii) in the january 2013 paper is basically all you need to know about protein synthesis, and knowing the roles of each form of RNA would also help

    Can someone outline the differences between natural selection, evolution and adaptation? I really don't understand the difference. I don't think that evolution is a difficult concept to get your head around, but I think they add loads of pointless crap that has no practical use.
    Also, could someone explain the key bits about conservation in/ex situ and international cooperation?

    well under the new spec i think the highest it has been out of 100 for full 150 ums is 86, so really you more than likely got full ums there


    Posted from TSR Mobile
    How did you know this? And is there anywhere that shows how many raw marks you need for 100%, 90% etc ums, on the ocr website they only show each grade :/

    Natural selection is the driving force behind evolution, think of it as the survival of the fittest argument! Only well-adapted creatures will survive, therefore, those genes will be passed on to the next generations (assuming they reproduce successfully), as a result, evolution occurs.

    Adaptations are just features, which species hold allowing them to adapt to their environments - fish have gills to breathe underwater.

    tRNA transfers the amino acids to the ribosomes in order to assemble different polypeptides

    I don't actually understand what the word transcription means. Is that a synonym for protein synthesis or a specific part of the process?
