WebChromatin makes sure the DNA stays organized, helps when the cell divides (making two cells), and it ensures the cell uses the correct part of our DNA to stay healthy. To unlock this lesson you ... WebThe basic unit of chromatin, the nucleosome, is an octamer of four core histone proteins (H2A, H2B, H3, and H4) and serves as a fundamental regulatory unit in all DNA-templated processes. The majority of nucleosome assembly occurs during DNA replication when these core histones are produced en masse to accommodate the nascent genome.

WebThe basic structural unit of chromatin is Nucleosome. It consists of 147 bp of DNA wrapped around a core of histone protiens.So the correct option is C. In view of the … WebApr 20, 2024 · Chromatosomes are fundamental units of chromatin structure that are formed when a linker histone protein binds to a nucleosome. The positioning of the linker histone on the nucleosome influences the packing of chromatin. The DNA + histone = chromatin definition: The DNA double helix in the cell nucleus is packaged by special proteins termed histones. The formed protein/DNA complex is called chromatin. The basic structural unit of chromatin is the nucleosome. See more Chromatin is a complex of DNA and protein found in eukaryotic cells. The primary function is to package long DNA molecules into more compact, denser structures. This prevents the strands from becoming tangled … See more Chromatin undergoes various structural changes during a cell cycle.
