Homework Answers
Transcription in eukaryotes occurs mainly through 3 steps:
1) Initiation
2) Elongation
3) Termination
All these processes require transcription factors. Eg: TFIIA, TFIIB, TFII3, etc.

Question 19: What sequences are important for the initiation of transcription in eukaryotes, and how does this compare to prokaryotic initiation? What sequence is important for the termination of transcription in eukaryotes, and how does this compare to prokaryotic termination? (There are very specific answers for each of these!)

Describe the process of Prokaryotic RNA transcription in molecular detail You must be able to describe the process and order of events in initiation, elongation, and termination. You must describe the catalytic/biological purpose function of the key proteins/elements in elongation -35 and -10 (Pribnow box) Promoters Sigma factors (does not matter which one) RNA Polymerase (including structure and subunits and mechanism) Rho-independent and rho-dependent termination How sequence composition affects promoter function

Last week we discussed the role of general transcription factors in forming the transcription initiation complex in eukaryotes. Next week we will look more closely at the regulation of gene expression and the role played by specific transcription factors. Prokaryotes and eukaryotes utilize very different mechanisms for determining which genes are turned on and off and when. In lieu of the prokaryotic operon model, eukaryotes employ a combinatorics approach utilizing both general and specific transcription factors. For this week’s forum,...
