In the case of eukaryotic cells, DNA attaches to proteins called histones, which are rich in arginine and lysine â these amino acids bear positive charges and form an ionic bond with the negative phosphate group of the DNA helix. This protein-DNA structure is called chromatin.
Chromosomes are made up of a DNA-protein complex called chromatin that is organized into subunits called nucleosomes. The way in which eukaryotes compact and arrange their chromatin not only allows a large amount of DNA to fit in a small space, but it also helps regulate gene expression.eBooks.his condensed form is approximately 10,000 times shorter than the linear DNA strand would be if it was devoid of proteins and pulled taut. However, when eukaryotic cells are not dividing â a stage called interphase â the chromatin within their chromosomes is less tightly packed.
