Detailed explanation-1: -A histone is a protein that provides structural support for a chromosome. Each chromosome contains a long molecule of DNA, which must fit into the cell nucleus. To do that, the DNA wraps around complexes of histone proteins, giving the chromosome a more compact shape.

Detailed explanation-2: -A nucleosome is a section of DNA that is wrapped around a core of proteins. Inside the nucleus, DNA forms a complex with proteins called chromatin, which allows the DNA to be condensed into a smaller volume.

Detailed explanation-3: -DNA molecules first wrap around the histone proteins forming beads on string structure called nucleosomes. Nucleosomes further [inaudible] and condense/gather to form fibrous material which is called chromatin.
