Transcription of a Gene Can Be Increased or Decreased According

Question

Transcription of a gene can be increased or decreased according to the:
A)combination of histone proteins found within the nucleosome.
B)coding sequences in the messenger RNAs for histone proteins.
C)proportion of arginine and lysine amino acids in the histone proteins.
D)combination of amino acid modifications in the histone tails.

Accepted Answer

The combination of amino acid modifications in the histone tails can affect the accessibility of the DNA to transcription factors and RNA polymerase, thus increasing or decreasing transcription of the gene. Choices A, B, and C are not directly related to gene expression regulation through histone modifications.
