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.

A homogeneous mixture (every part of the solution has the same properties) ,a heterogenous mixture (there are two or more phases present). one example of a mixture is air. >hope this helps..
