WebA chromosome is made up of genetic material (one long piece of DNA) wrapped around structural support proteins (histones). Histones organize the DNA and keep it from getting tangled, much like thread wrapped around a spool. But they also add a lot of bulk. WebYour DNA structure is made up of four base pairs: adenine (A), cytosine (C), thymine (T), and guanine (G). The bases form pairs (base pairs); A with T and C with G. The base pairs connect with a sugar molecule and a phosphate molecule (making a nucleotide) that form a spiral staircase (double helix). list the usa presidents

Web15 feb. 2024 · Chromatin consists of complexes of small proteins known as histones and DNA. Histones help organize DNA into structures called nucleosomes by providing a base on which the DNA can be wrapped around. A nucleosome consists of a DNA sequence of about 150 base pairs that is wrapped around a set of eight histones called an octamer. 1 WebA DNA strand is a long, thin molecule—averaging only about two nanometers (or two billionths of a meter) in width. That is so thin, that a human hair is about 40,000 times as wide.
