Histones are a family of basic proteins that associate with DNA in the nucleus and help condense it into chromatin. Nuclear DNA does not appear in free linear strands; it is highly condensed and wrapped around histones in order to fit inside of the nucleus and take part in the formation of chromosomes.nder the microscope in its extended form, chromatin looks like beads on a string. The beads are called nucleosomes. Each nucleosome is made of DNA wrapped around eight histone proteins that function like a spool and are called a histone octamer.
A histone octamer is the eight protein complex found at the center of a nucleosome core particle.It consists of two copies of each of the four core histone proteins (H2A, H2B, H3 and H4).s a result of the rotation, two ends of histones involved in DNA binding of the crescent shape H3-H4 are equivalent, yet they organize different stretches of DNA. The H2A-H2B dimer also folds similarly. The H3 2 -H4 2 tetramer is wrapped with DNA around it as a first step of nucleosome formation.
