The nuclear DNA does not come in the form of free linear strands, it is heavily condensed and enveloped around the histones so that to get fit within the nucleus and take part in the generation of chromosomes.
These are the basic proteins, and because of their positive charge, they get associated with the DNA. Under the microscope, chromatin appears like beads on a string. The beads are known as nucleosomes. Each nucleosome comprises DNA wrapped around the 8 histone proteins, which works like a spool and is known as a histone octamer.
