    How did you get 0.35?


    Posted from TSR Mobile
    1.4 X 250 = 350

    then 350/1000= 0.35 (as it wanted it in grams)

    I didn't know how to do it at first and then I remembered 1000ml=1l, so I used the same principle :|
    I think it's 2 marks though, so don't worry about it!

    Overall, this paper was harder than last year, particularly the second half and last year's paper was moderate. If it's been an A for the last two years, I think 65 would be reasonable

    I wrote what a mutation was. Different base triplet = different amino acid, different bonds form so 3D shape is different etc etc

    I think I mentioned that the RNA came into contact with the host cells DNA, then change in the base sequence and amino acid sequence coding for wrong polypeptides, changing the tertiary structure of the antigen so it can no longer function or something.
    Tbh I gave it my best shot, I had no idea what to put haha

    Think I wrote about primary structure being different so the amino acid sequence would alter then talked about how that would affect what polypeptides are coded for and what bonds you'd see in the tertiary structure.. maybe I'll scrounge some marks

    SAME OH NO, i thought you had to divide by 10, not 1000

    Did it state the conversion rate anywhere?
