Descrizione generale

Histones are a family of basic proteins that associate with DNA in the nucleus and help condense it into chromatin. Some histones function as spools for the thread-like DNA to wrap around forming a nucleosome. Each nucleosome is made of DNA wrapped around eight histone proteins that function like a spool and are called a histone octamer. Each histone octamer is composed of two copies each of the histone proteins H2A, H2B, H3, and H4. The chain of nucleosomes is then wrapped into a 30 nm spiral called a solenoid, where additional H1 histone proteins are associated with each nucleosome to maintain the chromosome structure.
