Nucleosomes are composed of "histones" class of molecules.

Explanation:

Histones usually presented in eukaryotic nuclei of cells which seemed as strong level of proteins that bundle and organize DNA into structural groups called nucleosomes in biological science.

They are chromatin's chief protein elements, functioning as spools along which DNA spins, and playing a major role in regulating genes. Five forms of histones have been recognized:

H1 (or H5), H2A, H2B, H3, and H4; H2A, H2B, H3, and H4 are the main histones and H1 and H5 are the linker histones.
