    6281   DNA Repair  The Process of Restoring DNA After Damage. Genomes Are Subject to Damage by Chemical and Physical Agents in the Environment (e.g. Uv and Ionizing Radiations Chemical Mutagens Fungal and Bacterial Toxins Etc.) and by Free Radicals or Alkylating Agents Endogenously Generated in Metabolism. DNA Is Also Damaged Because of Errors During Its Replication. a Variety of Different DNA Repair Pathways Have Been Reported That Include Direct Reversal Base Excision Repair Nucleotide Excision Repair Photoreactivation Bypass Double Strand Break Repair Pathway and Mismatch Repair Pathway. 
    6338   Chromatin Remodeling  Dynamic Structural Changes to Eukaryotic Chromatin Occurring Throughout the Cell Division Cycle. These Changes Range From the Local Changes Necessary For Transcriptional Regulation to Global Changes Necessary For Chromosome Segregation. 
    43967   Histone H4 Acetylation  The Modification of Histone H4 by the Addition of an Acetyl Group. 
    43968   Histone H2a Acetylation  The Modification of Histone H2a by the Addition of an Acetyl Group. 
    35267   Nua4 Histone Acetyltransferase Complex  A Complex Having Histone Acetylase Activity On Chromatin As Well As Atpase DNA Helicase and Structural DNA Binding Activities. the Complex Is Thought to Be Involved in Double Strand DNA Break Repair. Subunits of the Human Complex Include Htatip/tip60 Trrap Ruvbl1 Buvbl2 Beta Actin and Baf53/actl6a. in Yeast the Complex Has 13 Subunits Including the Catalytic Subunit Esa1 (homologous to Human Tip60).
