Impact of Chromatin on Transcription
About the Lecture
The lecture Impact of Chromatin on Transcription by Georgina Cornwall, PhD is from the course Gene Regulation.
Included Quiz Questions
Which of the following is the most likely purpose of DNA methylation?
- DNA methylation ensures that once a gene is turned "off," it will remain "off."
- DNA methylation ensures that the nucleosome will quickly form and assist in mRNA formation.
- DNA methylation ensures that once a particular gene is transcribed, the mRNA is saved and used over and over again.
- DNA methylation ensures that a gene functions without interruptions.
- DNA methylation ensures that DNA unwinds from the histone.
Which of the following is NOT associated with chromatin remodeling?
- RNA methylation
- Nucleosome sliding
- Nucleosome remodeling
- Nucleosome removal
- Histone replacement
Which of the following is CORRECT regarding histone tail acetylation?
- It facilitates chromatin decondensation and allows DNA transcription.
- It facilitates chromatin condensation to allow chromosome formation.
- It prevents decondensation of the chromosome.
- It prevents the binding of transcription factors and activators to the gene.
- It participates in the tight coiling of the DNA duplex around the histone core.
