The structure of prokaryotic chromosomes is circular DNA tightly wound around histones.
Chromosomes have a basic structure: a DNA molecule that has portions wrapped in grains formed by eight molecules of a protein called histone. Each histone grain with coiled DNA is called a nucleosome.
A chromosome can be demarcated along its length into thousands of regions called genes. The function of chromosomes is to control cell functions. In addition, they carry an individual's genetic information through genes.
