2007 Unit 4 Exam Thoughts
astarael:
i'm 98% certain it did say mutates. maybe they'll award marks for both B and C - they did that for one question on the midyear.

what was alternative B?
Besides, the mutation rate of nuclear DNA can be varible, it can be fast or slow depending on the selective pressures of the phenotype that arises from such mutations.
mtDNA mutates at a predictable rate
ninwa:
wasn't B something like mtDNA has more genes than nuclear DNA?
sigh, the more I think about it the more I realised how much I fluffed that exam. biology should get marked up more lol

Yeh bio can be a bit rough sometimes, if the performance was better, we might see more sclaing, bu unfortunately, like PE and HHD, it must go down.
Yeh alternative B is not correct. The human genome has more genes than the number of nucleotide base pairs in mtDNA, so it's a fair difference
ninwa:
does anybody have a copy of the exam btw?
i forgot to steal one off one of the teachers :P
