Histones are basic proteins that bind to DNA in the nucleus and aid in its condensation into chromatin.
Nuclear DNA is extremely condensed and wrapped around histones in order to fit inside the nucleus and assist in chromosome creation. Histones are positively charged basic proteins that may attach to negatively charged DNA.
Some histones function as spools around which the thread-like DNA wraps.
5 major types of histones:
H1, H2A, H2B, H3, and H4 are the five primary histone types.
