Quiz zum Vortrag
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.
