The most general principle ruling acid strength can be stated thus: strong acids have relatively stable conjugate bases. In general, the more stable the conjugate base, the stronger the acid. An important thing to remember is that stability and reactivity are inverse. The more stable a substance is, the less ...

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. The other histone proteins are: H1, H2B, H3 and H4. See more Histones are proteins that package DNA into nucleosomes. Histones are responsible for maintaining the shape and structure of a … See more H2A consists of a main globular domain, an N-terminal tail and a C-terminal tail. Both tails are the location of post-translational modification. Thus far, researchers have not identified any secondary structures that arise in the tails.
