Question

Quizplus · Accepted Answer

Chromatin structure includes nucleosomes, which are the basic unit of DNA packaging, consisting of DNA wrapped around histone proteins. The 30 nm fiber is a higher-order structure formed by the folding of the nucleosome chain, and the 200 nm filaments represent even higher-order folding, contributing to the compactness of chromatin in the cell nucleus. Therefore, all of the options listed are correct levels of chromatin structure.
