Question

. What is acetylation and methylation of histone? How does it help in DNA replication and transcription?

​

Answer 1

Answer:

Explanation:

The mechanism for acetylation and deacetylation takes place on the NH3+ groups of Lysine amino acid residues. These residues are located on the tails of histones that make up the nucleosome of packaged dsDNA. ... Thus, acetylation of histones is known to increase the expression of genes through transcription activation.

Answer 2

Answer:

Heya❤️

Histone acetylation alters chromatin structure.

Acetylation of histones alters accessibility of chromatin and allows DNA binding proteins to interact with exposed sites to activate gene transcription and downstream cellular functions.
