Your Thoughts On Biology 2010 Exam 2

[sillysmile]

Aced the transcription, translation, speciation, natural selection. But I have gone over some of the questions in my head and realised I have made some pretty stupid mistakes arghhh wish I could rewind!

couldn't agree more.

 i stupidly wrote one codon codes for more than one amino acids ! but its the other way around noooooo

lol don't worry its 1 mark

haha yeah luckily

Wtf i wrote that more than 1 codon can code for diff amino acids.

EDIT
wait i wrote that diff codons code for the same amino acid.

hey what did we put for qn 24 on MC? the one with the flagella? i chose convergant evolution

same.

i dont think it was convergent as in the stem on the question it had a tree which showed they came from a same ancestor

Yeah, and 25 was A, the cell wall one...

meeeeee too

I chose convergent too but one of my friends said they werent subjected to the same environmental pressures - they were in separate enviroments - salt water and fresh water?

i think the main idea here was that flagell awere required for swimming, regardless of the medium...

that evidences convergent evolution.
as the same/a similar feature had been selected for.

[The Detective]

and they had the same function, different basic structure = analagous = convergent

I feel sorry for people who didnt know transcription/translation properly...

8 marks on name this process... describe the steps...for both of them too

Haven't seen an exam like that before and i wouldnt of expected it

whats translation? I know what transcription is ... (joking)

about that centromere question, I wrote about the significance of the centromere
being major evidence supporting the diversion of the chimpanzees from the humans
since the combination of the two chromosomes would have resulted in organisms
with features that define a 'homo sapien' - eg, larger brain case, bipedalism etc

whats your take on this definition?
