OCR A2 Biology textbook wtf moment

Scroll to see replies

yeahhh then im going to try past papers because every1 who done well in bio tells me that they are key.

That's key to most subjects I think - you can never do enough past papers! Also look at the past papers from the old specifications as there'll be very similar sorts of questions :smile:

hey,

anyone notice the mistake on p107 - figure 3 - part 2 - where the amino acid tyrosine is brought to the ribosome to the codon AUA?
AUA doesn't actually code for this AA, it codes for lsoleucine?

could someone confirm this pls?
thanks

OK, Im probably just being stupid but, page 107 in the stretch and challenge bit. The questions answers on the back of the book (275) contradict what the paragraph is getting at. Im wondering if anyone else has noticed or it OCR doing that fabulously annoying thing of hiding questions in another question, that or I just don't get it!
Thanx for any help.
