Anyone do the OCR Biology AS today? How did you find it and what answers did you get? Personally, I panicked because I left revision last minute and just dreaded the whole thing as I did it.

Same I only managed to do revision for half of module 2 because I was prioritising my other subjects :/ I thought it didnt go too well. Do you remember any answers you got?

For the similarities and differences between DNA nucleotide and ATP:
I got that similarities:
both have at least one phosphate group
both have phosphodiester bonds
Differences:
ATP has more phosphate groups
ATP has adenosine and that DNA nucleotide had adenine.
These were guesses though so I don't know? What did you get?
And do you remember any other answers?

I remember talking about how DNA has deoxyribose as the pentose sugar and ATP has ribose. I said they both have adenine :/// But in terms of phosphate groups i said the same thing as you.

ATP has ribose sugar while DNA has deoxyribose sugar. But question do you think I will lose marks if I say phosphate molecules instead of groups? (ps: I don't do chemistry😂😂)
