The term “chromatin” refers to the mixture of protein and DNA which forms the chromosomes found in the cells of humans and other organisms. Most proteins like histones can package the high amount of DNA in a genome and make it fit into the cell nucleus. The total length of the DA is about 5 to 6 feet long, which cannot fit into the cell’s nucleus in an orderly fashion. That’s why the DNA molecules first wrapped around the histone protein and formed beads on the string structure, known as nucleosomes. These nucleosomes further condense to form a fibrous material, chromatin. During the replication and duplication of cells, the chromatin further condenses and becomes like chromosomes, which are visible under a microscope and separated into daughter cells during division.
