contents of the nucleus of a cell. It has 4 main functions: to package DNA into a smaller volume to fit in the cell‚ to strengthen the DNA to allow for mitosis‚ to prevent DNA damage‚ and finally‚ to control gene expression and DNA replication. The structure of chromatin consists of a series of DNA wrapped around histones to form nucleosomes. But during mitosis the chromatin is compacted to form chromosomes. Each human has 23 pairs of chromosomes consisting of a sugar/phosphate backbone and nitrogenous base
