The narrator eventually succumbed to the loud beat and confessed his crime because he could no longer take the guilt building up inside of him.
Answer:
B) decreased chromatin condensation
Explanation:
The addition of acetyl groups to the histone tails results in a less packed state of chromatin. The acetylation of multiple Lys residues in the amino-terminal domains of histones H3 and H4 reduces the affinity of the entire nucleosome for DNA. It occurs since acetylation reduces the total positive charge present on histone proteins. Histone proteins are positively charged and pack the negatively charged DNA around them. Therefore, increased acetylation results in decreased condensation of chromatin. The loosely packed DNA is accessible by RNA polymerase and transcription factors for gene expression.
