Histone Modification
Histone modification refers to chemical alterations that occur on histone proteins, which are responsible for packaging and organizing DNA within the nucleus of eukaryotic cells. These modifications can include methylation, acetylation, phosphorylation, ubiquitination, and other changes that can impact gene expression and chromatin structure. Histone modifications play a crucial role in regulating various cellular processes such as DNA replication, repair, and transcription.
