How do promoters in Archaea and Eukaryotes differ?
Homework Answers
In genetics promoter is a region that initiates DNA transcription. Promoters are located near the transcription starting sites of the gene on the same strand and the upstream on DNA.
Promotor of eukaryotes and archaea are mostly same but slightly differ. Tha life time of TBP- DNA interaction differs significantly between eukaryotes and archaea. Eukaryotic TBP-DNA interaction is charecterised by linear, stepwise bending mechanism with an intermediate state distinguished by a distinct bending angle. TF(II)B specifically stabilizes the fully bend TBP-promoter DNA complex. In archaea TBP-DNA interaction is extremely dynamic and TBP from archaeal organism sulfolobus acidocaldarius strictly requires TFB for DNA bending

If eukaryotes arose from within archaea, what does this mean in terms of the 'phyl' of archaea? Are they mono-, para-, or polyphyletic? How about eukarya?

How do prokaryotes and eukaryotes differ with respect to the number of open reading frames that are contained in a typical mRNA? Why does this difference make sense in view of the translation initiation strategies used by each type of organism? What consequences does this difference have for the regulation of coordinated gene expression in the two types of organisms—for example, how might a key regulator turn on a suite of related genes in prokaryotic or eukaryotic cells?
