For eukaryotic transcription to begin, the initiation complex must assemble. What is the function of TFIID?
Homework Answers
In Eukaryotes, RNA polymerase II doesn't directly bind to the promoter. First of all several transcription factors bind to the promoter. TFIID is the first transcription factor which bind to the promoter at TATA Box. TFIID composed of Tata box binding protein (TBP) and about 14 TBP associated factors (TAFs). The binding of TFIID initiates the binding of other transcription factors like TFIIB, TFIIH, TFIIF etc. These transcription factors make the pre initiation transcription complex.

In eukaryotic transcription what is the function of a chromatin remodeling complex? Chromatin remodeling complexes form nucleosome structures at protein-coding regions to lock genes from transcription when they are inactive. Chromatin remodeling complexes clear nucleosomes away from enhancer regions, so that transcription goes at full rate. Chromatin remodeling complexes reform DNA structure after transcription is complete to keep it stable . Chromatin remodeling complexes clear nucleosomes away from promoter regions, so that transcription initiation complexes can form and 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,...
