DNA wraps around a histone octamer that is composed of one (H3–H4) 2 tetramer capped by two H2A–H2B dimers. Together with the linker histone H1, this forms the nucleosome — the basic ...

Histones are a family of basic proteins that associate with DNA in the nucleus and help condense ... where additional H1 histone proteins are associated with each nucleosome to maintain the ...
