I thought it was none coding regions in chromsomes in the nucleus.



All in all that was both the hardest and easiest exam ever.
So many questions were so stuffed up.

i thought sections of the multiple choice was more challenging than 2010 but extended response was similar, the horse questions was stupid as well as the stupid where is RNA polymerase found .. i wrote the nucleus ....  can someone please put up suggested solutions ?

[Charmz]

I'm pretty sure RNA polymerase is what allows transcription to occur. So yes it would be in the nucleus. Correct me if I'm wrong.

that's what i thought but the nucleus wasnt one of the structures labeled i thought it was out of the trna and the ribosome

[ezye21]

mmm to be honest the nucleus is still a structure in the cell...

[ezye21]

solutions anyone ?

The PDF of the exam

What about the dog question?? BbTt X BbTt or BbTt X bbtt?? both combinations could give rise to all the phenotypes :S

yeah true. the structure was the mRNA which was in the nucleus

When Charmz uploads them all, I'll pdf it and edit it into his first post/OP and clean the duplicates up. Thanks for doing it, you're awesome

BTW I'm not a guy.

no it was a 1:1:1:1  phenotype and thus it had to be a heterozygous for both traits crossed with a homozygous recessive for both traitsto give that ratio
there for it was BbTt x bbtt

i dont think it said it was 1:1:1:1 anywhere

They should give both because 4 samples isn't exactly an accurate sample size to be able to determine that!

[geo3. z]

Yeah its definitely the nucleus. I checked my bio tectbook and Wikipedia

That was a real bitch of a question though. Got me flustered until I thought i couldve been a trick qusetion, making u think it wsa a listed structure

[geo3. z]

for that question did u say the 'T' trait was dominant or recessive
