comment Why does the T7 RNA Polymerase require a reducing environment ie. DTT
How strange. I'm looking at the crystal structure (1QLN) and there aren't a lot of cysteines near the active site. Will have to take a look at those papers.

comment Why does Penicillin only affect bacterial cell walls
I don't think that this is necessarily correct. The beta-lactams doesn't inhibit the synthesis but rather the reorganization of the peptidoglycans. The rigidity of the now static wall then prevents cell division.

@Garima Kushwaha. Does this count? ncbi.nlm.nih.gov/pmc/articles/PMC2836557

comment How to clone and sequence a gene transcript of unknown sequence?
Having the hormone sequence does help a bit. While not entirely unbiased, you could try to enrich your sequence by amplifying from a conserved region.

comment Do larger multicellular organisms have an increased risk of mutation and thus cancer?
I would say that the question is more complicated since it really depends on the number of generations of cells. For instance muscle cells rarely get cancel but they also rarely divide.
