Lesson Summary. Chromatin is the special complex of DNA and protein that condenses the genome so that it can be packed into the tiny nucleus. First, DNA is wrapped around histone proteins. Then, a group of histones comes together to form a nucleosome. Finally, the string of nucleosome beads is coiled to condense the DNA even further.
The primary protein components of chromatin are histones that compact the DNA. Chromatin is only found in eukaryotic cells (cells with defined nuclei). Prokaryotic cells have a different organization of their DNA (the prokaryotic chromosome equivalent is called genophore and is localized within the nucleoid region).The structure of chromatin depends on several factors.The overall structure depends on the stage of the cell cycle.he primary functions of chromatin are 1) to package DNA into a smaller volume to fit in the cell, 2) to reinforce the DNA macromolecule to allow mitosis, 3) to prevent DNA damage, and 4) to control gene expression and DNA replication.
