Summary. DNA is tightly packed in the nucleus of every cell. DNA wraps around special proteins called histones, which form loops of DNA called nucleosomes. These nucleosomes coil and stack together to form fibers called chromatin.Chromatin in turn forms larger loops and coils to form chromosomes.ummary.
