The DNA + histone = chromatin definition: The DNA double helix in the cell nucleus is packaged by special proteins termed histones. The formed protein/DNA complex is called chromatin. The basic structural unit of chromatin is the nucleosome. A chromosome is a DNA molecule with part or all of the genetic material of an organism. Most eukaryotic chromosomes include packaging proteins which, aided by chaperone proteins, bind to and condense ..

DNA exists in Chromatin form in the nucleus. The chromatin condenses to form Chromosomes during cell division.
Inside the nucleus
The chromatin in the nucleus forms a 'beads-on-string' structure or Nucleosome. The 'beads' are octamer histone proteins and the 'string' is the double-stranded DNA. About 147 base pairs wrap around the 8-part histone protein to form a nucleosome. The nucleosomes condense to form a chromatin fiber.
Chromatin fiber organises into Chromosomesupon cell division. The chromatin is elaborately arranged and paired in mitosis. Sister chromatids are formed in case of meiosis along with pairing. After division, the DNA returns to it's looser chromatin form.
