WebChromatin: is the carrier of genetic information. It is a complex structure composed of DNA and proteins and localized in the cellular nucleus. Chromatin remodeling machines: require energy in the form of ATP and induce changes in conformation at the level of the nucleosome or more globally over large chromatin domains. WebMar 14, 2016 · Chromatin is formed by the first two levels of coiling of DNA. Firstly, a strand of DNA is wrapped around proteins called histones. As the DNA wraps around histone proteins small beads are formed along the DNA strand called nucleosomes. One nucleosome is around 10 nm wide. DNA + histone = nucleosome
