What are the four mechanisms that mediates transcriptional activation in addition to RNA interference during during the regulation of eukaryotic gene expression
Homework Answers
Let us list them and describe them:
- Methylation system. This requires cytosines to be methylated in order to block transcription of a certain gene
- Polymerase complex assembly. Proper assembly is a crucial procces for transcription to occur, the regulation of this process is a mechanism to regulate transcription per se
- Transcription factors mechanism. Transcription will only start if the proper factors and enhancers are brought in place, regulation of such factors and enhancers availability regulates the transcription of the site
- Chromatin state. Methylation or acetylation of histones regulates the tightness of such histones over DNA, acetylation promotes expression while methylation prevents it

Which of the following mechanisms to regulate gene expression are observed in eukaryotes, but are not generally observed in prokaryotes? Choose all that apply. Genes are grouped into operons, which allows transcriptional regulation to turn them all on together. RNA silencing selectively targets mRNA and destroys it to prevent further translation. Proteins can be activated or deactivated as a form of post-translational regulation. Epigenetic regulation can open or condense sectiosn of a chromosome, regulating which genes are transcribed. Regulatory proteins...

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,...

Small single‐stranded RNAs called micro RNAs (miRNAs) are about 21 nucleotides long and act to inhibit expression of specific genes. Describe how such RNAs are made and the mechanisms responsible for their inhibition of gene expression. During formation of sperm, activation of selfish genetic elements called retrotransposons is inhibited by a special class of short interfering RNAs (siRNAs) called piRNAs that are slightly longer than miRNAs. Based on your knowledge of RNA interference mechanisms, how might piRNAs inhibit retrotransposons? What...
