Nucleosome,molecular model. A nucleosome is a subunit of chromatin,the substance that forms chromosomes. It consists of a short length of DNA (deoxyribonucleic acid,red and blue helix) wrapped around a core of eight histone proteins (centre). Here the secondary structure of the proteins is shown. The structure of the nucleosome allows large quantities of DNA,the genetic material,to be packaged into a cell's nucleus | |
