Histones are proteins that control gene function by attaching salt links to exterior regions of DNA. Argentines is an amino acid whose side chain is often found on the exterior of histones
A chromosome's structural support is provided by a protein called a histone. Long DNA molecules found on each chromosome must fit into the cell nucleus. This is accomplished by the DNA wrapping around histone protein complexes, giving the chromosome a more compact form.
The eight-protein complex known as a histone octamer is what makes up the nucleosome core particle. Each of the four main histone proteins is present in two copies in this structure (H2A, H2B, H3 and H4). When a tetramer, which has two copies of both H3 and H4, interacts with two H2A/H2B dimers, the octamer forms.

Answer:
Explanation:
Given the details, we can say that
Pure methanol is a volatile solvent as the vapour pressure has a high value. This means that methanol - methanol intermolecular forces are weak in comparisson to water - water forces. When having about 30% of water in a methanol mixture, the mixture Pv decreased, showing that it is not a volatile mixture, so then there are strong intermolecular interactions between methanol - water, part of it due to the hydrogen bonds.
Take the given 2.00 moles of hydrogen then divide it by 1 mole of hydrogen. Second you want to multiply the answer by 22.4L. Giving you an answer of 44.8L of hydrogen
The neutralization of the base with an acid will result to the formation of salt and water. In this case, a mole of strong acid will have one halide that will react with the Na atom. Since there are two Na atoms in each of the molecule of Na2HPO4, this will need 2 halide atoms.
