WebDNA is negatively charged, due to the phosphate groups in its phosphate-sugar backbone, so histones bind with DNA very tightly. Figure 1: Chromosomes are composed of DNA tightly-wound around histones. WebEach nucleotide consists of a phosphate group, a nitrogenous base—adenine (A), thymine (T), cytosine (C), or guanine (G)—and deoxyribose. DNA's sugar, deoxyribose, has five carbon atoms, which are connected to each other to form what looks like a ring. Four carbons plus an oxygen are part of the five-sided ring.
