Definition

The post-replication modifications are conferred on newly synthesized DNA while being packaged into  chromatin. They include the methylation of cytosine residues on hemi-methylated DNA and also de novo methylation. The marking of histone tails with post-translational modifications like acetylation, methylation, phosphorylation, and ubiqutination ( Ubiquitin and SUMO) and also the insertion of histone variants like H2A.Z, macroH2A, H2A.X or H3.1, H3.2, and H3.3 into  nucleosomes are also carried out after replication.
