Answer:
A. The tails do not interact with the DNA
Explanation:
The acetylation refers to the transfer of the acetyl group from Acetyl-CoA to the N-terminal of the histone protein.
Lysine residues (positively charged amino acid) are present at the end of the N-terminal of the histone protein which is neutralized by the acetyl group.
This loses the compaction between the positively charged histone and the negatively charged DNA and the DNA becomes more relaxed. This relaxed state allows the transcription factors to easily bind the DNA and therefore the DNA becomes transcriptionally active.
Thus, Option-A is correct
The answer does the question is : C
It would be a catalyst. They help increase the rate of chemical reactions.
Answer:
G1 phase causes the cell to grow in size and produce new organelles, which prepare for S phase, when the DNA replicates. Answer 3: Cells will duplicate or copy their DNA right before they divide. The process of cell division is called mitosis.
