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.uring this stage of the cell cycle this makes the individual chromosomes in many cells visible by optical microscope. In general terms, there are three levels of chromatin organization: 1  DNA wraps around histone proteins forming nucleosomes; the beads on a string structure (euchromatin).
