WebbThe histone octamer is made up of two dimers of H4/H3 and surrounded on either side by an H2A/H2B dimer. This dimer is capable of winding 147 base pairs of DNA around itself, in two left-handed loops, forming a structure known as a nucleosome. Each nucleosome is separated by 20-30 base pairs of DNA, and can also be referred to as 'linker DNA' [4].

And so, chromatin is made up of DNA, histone proteins, and non-histone proteins. And there are repeating units in chromatin, called nucleosomes, which are made up of 146 base pairs of double helical DNA that is wrapped around a core of eight histones.

WebbHistone genes are among the most highly cell-cycle-regulated genes [54] because cells need to ensure a high demand of histones during replication, but must make sure that these levels are quickly down-regulated when replication slows down or is blocked, to avoid the deleterious effects of free histones on cell survival.
