Abstract
Chromosomes are structures within the nuclei of eukaryotic cells that contain deoxyribonucleic acid (DNA) combined with proteins. Chromatin refers to the material of the chromosomes – DNA plus proteins. Before DNA replication, each chromosome contains a single, very long DNA molecule that basically runs from one end of the chromosome to the other. Core histone proteins package segments of this DNA molecule into nucleosomes, and linker histones further compact the resulting ‘string of beads’ into a 30‐nm chromatin fibre. In mitotic chromosomes, scaffold proteins fold the chromatin fibre into loops along its length. Chromosomes are very dynamic structures and take several forms, but the basic organisation is always related to the structure of mitotic chromosomes. The location of chromosomes in the nucleus, the nature of the loops and modifications to the chromatin fibre are thought to be important in determining which DNA sequences are made available for transcription and other processes.

The chromatin network are fibrous thread like structures present in the nucleus of cell. During cell division, the chromatin network becomes thick and ribbon like and is known as chromosome. It is the bearer of hereditary characters
