Silly question (I know) but I need to be sure...

We dont have to learn what MRSA stands for do we?
Just the example of the whole antibacterial resistance thingy, right?

no we don't :smile:

specification says "Antibiotic resistance in terms of the difficulty of treating tuberculosis and MRSA"

oh my god i have no idea what a start or stop codon is :s-smilie:

so how come that makes it 384 or 387 as well? surely that would make it 383 :/

The stop and start codons are worth 3 bases each

so 381 + 3 or 6 = 384 or 387

ok, thank you, so do all genes have start and stop codons? wouldn't you always add 6 then?

Uuumm... dont know about that, I think different people are taught slightly different things so that why the mark scheme you were looking at allowed 3 different answers.
Just stick to the way you are doing it and it should be fine :smile:

oh i wouldn't worry if you have a textbook haha, i don't have one though so thought i'd best get some structure to my revision going, i don't want anything filling up my head that we don't actually need to know!

Worried about this, was confident on the last one for an A and ended up with a B. By no means bad, but I really want that A, does anyone have any predictions on what's going to come up? :smile:

Well if it makes you feel better i do unit 5 biology and i hadn't heard the word start/stop codon till this unit. It's part of the unit 5 syllabus but certainly not unit 2.
