A complex of DNA, histones and nonhistone chromosomal proteins which make up the chromosomes found in eukaryotic nuclei[1]. 145 bp of DNA is wound into a left-handed superhelix[2] around 8 histones with up to 80 bp linking to the next "bead on a string". Each of these repeating units is a nucleosome.
