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.
Best Answer: Chromosomes are organized structures of DNA and proteins that are found in cells. A chromosome is a singular piece of DNA, which contains many genes, regulatory elements and other nucleotide sequences.Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions.hen you consider that there are two copies of each chromosome, and that each copy of each gene on the chromosome might be slightly different from the other, you have the possibility of two slightly different proteins being produced from them.
