<P> Chromatin is a complex of macromolecules found in cells , consisting of DNA , protein , and RNA . The primary functions of chromatin are 1 ) to package DNA into a more compact , denser shape , 2 ) to reinforce the DNA macromolecule to allow mitosis , 3 ) to prevent DNA damage , and 4 ) to control gene expression and DNA replication . 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 ) . </P>
