Phosphorylation of histone tails
WebIn recent years, the covalent modification of histone tails has emerged as a crucial step in controlling the transcription of eukaryotic genes. Phosphorylation of the serine 10 residue of the N-terminal tail of histone H3 is crucial for chromosome condensation and cell-cycle progression during mitosis and meiosis.
