Many transcriptional activators are proteins with a DNA-binding domain (DBD) and an activation domain (AD). Explain how each domain contributes to transcriptional initiation. Would you expect repressors to also have each of these domains?
Once an RNA polymerase has initiated transcription, it will release the sigma factor or sigma subunits or bind other proteins known as elongation factors before it begin moving down the DNA template doing strand elongation. Briefly explain why this is necessary - why cant RNA polymerase + sigma factor do all of transcription?
The concentration of free glutamine affects transcription of the enzyme glutamine synthetase in E. coli. Describe the mechanism of this effect.
TRUE OR FALSEErrors in transcription can lead to silent mutations encoding the same amino acid or an altered protein that retains its functionality.
Heparin is a polyanionic polysaccharide that blocks elongation by RNA polymerase. But heparin inhibits only when added before the onset of transcription and not if added after transcription begins. Explain this difference.
The mechanism for RNA-induced transcriptional silencing of heterochromatic DNA is paradoxical. For example, how does it make sense that centromeric DNA in fission yeast first needs to be transcribed before it can be transcriptionally silenced?
Why is protein N important in the transcription of cII?
DNA methylation status is associated with transcriptional activity. First, describe the specific mechanism by which DNA methylation can control gene activation. Next, hypothesize what would happen to transcription in a cell that expressed an nonfunctional maintenance methyltransferase. Please give me long detailed answer.
Heparin is a polyanionic polysaccharide that blocks initiation by RNA polymerase by virtue of its binding to double-stranded DNA. But heparin inhibits only when added before the onset of transcription, and not if added after transcription begins. Explain this difference.
Using the transcription unit diagrammed below, in which exons are represented by blue boxes and introns are represented by the connecting lines. You discover a single base deletion in region E of this DNA sequence. Regarding transcription, this mutation will likely: 1.) Result in an alteration to the mRNA sequence. 2.)Have no effect on transcription or the mRNA sequence 3.)Prevent transcription at the TATAA box 4.) Result in an increase or decrease in the amount of mRNA transcribed
What does it mean to study the subcellular localization of a protein? What are two techniques that could be used to study the subcellular localization of a protein? Then specify how each of these techniques could be used to study a transcription factor in liver cells
