The structure formed by wrapping DNA around a histone core is called a nucleosome.
A section of DNA wrapped around core histoneproteins is termed a nucleosome. The protein and DNA complex inside the nucleus is called chromatin. This is a thread-like structure due to the formation of which DNA is condensed into a small volume.
The structure of chromatin appears to be like 'beads on a string under a microscope. The beads are the nucleosomes. The nucleosomes are small structures with a diameter of approximately 11 nm. Also, nucleosomes are known to be the fundamental subunits of chromatin.
In each nucleosome, a set of eight histone proteins are present. There are about two turns of DNA in each nucleosome around eight histone proteins. These histone proteins are known as histoneoctamer. There are two sets of each histone protein namely, H2A, H2B, H3, and H4.
Therefore, the structure formed by wrapping DNA around a histone core is called a nucleosome.
