This nucleotide contains the five-carbon sugar deoxyribose, a nitrogenous base called adenine, and one phosphate group. Together, the deoxyribose and adenine make up a nucleoside (specifically, a deoxyribonucleoside) called deoxyadenosine.ithout the phosphate group, the nucleobase and sugar compose a nucleoside. The phosphate groups form bonds with either the 2, 3, or 5-carbon of the sugar, with the 5-carbon site most common.
The nucleosome is the fundamental subunit of chromatin. Each nucleosome is composed of a little less than two turns of DNA wrapped around a set of eight proteins called histones, which are known as a histone octamer. Each histone octamer is composed of two copies each of the histone proteins H2A, H2B, H3, and H4.
