WebDec 11, 2024 · Nucleosomes are the basis of chromatin organization in eukaryotes. Nucleosomes are assembled by the sequential association of two histone H3–H4 dimers and two histone H2A–H2B to form an octameric protein complex that wraps about 147 base-pairs of DNA [].Nucleosome assembly requires the aid of protein chaperones that … H2A is considered a core histone, along with H2B, H3 and H4. Core formation first occurs through the interaction of two H2A molecules. [3] Then, H2A forms a dimer with H2B; the core molecule is complete when H3-H4 also attaches to form a tetramer. Sequence variants [ edit] Histone H2A is composed of … See more Histone H2A is one of the five main histone proteins involved in the structure of chromatin in eukaryotic cells.
