Histonok
Histonok is a term encountered in some non-English scientific texts as an alternative transliteration or inflected form of histones, the protein components around which DNA wraps to form chromatin. In English-language biology, the standard term is histone (plural histones). When used, histonok refers to the same protein family, typically including the core histones H2A, H2B, H3 and H4, which assemble into a histone octamer around which about 146 base pairs of DNA are wrapped to form a nucleosome. The linker histone H1 associates with the DNA between nucleosomes to help stabilize higher-order chromatin structure.
Roles and functions of histones include packaging DNA into compact, organized chromatin and regulating access to
Variant histones and histone chaperones add further complexity. Variants like H2A.Z, H3.3 and CENP-A can replace
History notes that histones were first isolated in the late 19th to early 20th century, and the
