Hi I've searched this site, the past paper request thread and googled it, but I can't find the 2007 biochemistry papers anywhere. If anybody could point me in the right direction I'd appreciate it! Thanks
Our school usually does the transition metals option, so they barely have any biochemistry papers. Our head of science has contacted the exam board to see if she can get them, but if they do come, it'll be too late.
Ok... i'll pm it to you when i have a spare moment to type it out (if i can find my version, that is). are there any others that you would like if i can't find that one?
do you have to remember ALL the structures such as maltose, alpha glucose etc or will they be shown in the exam
You won't be asked to draw them from scratch. They will be shown, but you will have to know how to distinguish between them.
How are you guys revising for this unit? I've just got a copy of the spec and I'm going through the points one at a time using my textbook. I've read through the whole book numerous times so this method is quite effective. Especially as it cuts through all the **** found in this textbook
can anyone give me a good roundup on translation, replication and transcripition? (e.g. a couple of steps for each that is enough to get me full marks in the exam)
replication - DNA unzips, nucletides attached to unzipped end by DNA polymerase transcription - copying of DNA (with RNA polymerase) to mRNA - moves to ribosome translation -rRNA moves along mRNA, joining the amino-acids into polypeptides
