What is histone code
Answer: The modification of gene expression as a consequence of chemical alteration to the tails of histone proteins
Justification:Chromatin is composed of genes, chromosomal protein and histones in eukaryotic cell. The histone tails are suspecitible to covalent modification or in a simple term chemical alteration. Histone code is a chemical alteration taking place via phosphorylation, ubiquitylation, sumoylation, acetylation and methylation which act as marks for the recruitment for various protein complexes to regulate different genetic functions, such as gene expression, DNA replication, and chromosome segregation.
