Chaperoning Histones during DNA Replication and Repair

WebApr 9, 2024 · Histones are a type of basic protein that binds to DNA in the nucleus and helps it condense into chromatin. Nuclear DNA does not exist in free linear strands; it is highly condensed and wrapped around histones in order to fit inside the nucleus and participate in chromosome formation. WebHistones are a group of proteins associated with DNA in the nucleus and aid in condensing them into chromatin. This nuclear DNA is highly condensed and surrounds the histones in first order to be able to get accommodated in the nucleus and participate in the chromosomal formation. reborn in naruto as madara’s grandson https://dimagomm.com
