Saw this on a past year rjc promo paper:
Distinguish between repression and feedback inhibition caused by an end product of a biosynthtic pathway. Briefly state how regulatory phenomena complement each other to provide for the efficient regulation of metabolism. [5]
It's basically testing on control and enzymes (and I'll die horribly if this question comes out ._. )
Anyone that wants the answer key can photocopy from me on mon or smth, I'm lazy to type out ><
Yeppp then for this year rjc bio promo essay questions:
1(a)difference in structure between pro and eu genome
(b) role of promoter, telomere and centromere
(c) describe control at post-transcriptional level
2. (a) explain the evidence for semi-conserative replication
(b)explain the role of mRNA in protein synthesise
(c) describe the genetic code
The marks are 6,6 and 8. Anyway the second question is roughly like that, my friend could only remember exactly the one that he did, which is the first one.
Heh hope it's useful for those trying to spot essay questions ~
