Chromosome

In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
What is a Chromosome?

Chromosomes are the basic building blocks of life where the entire genome of an organism is essentially organized and stored in the form of DNA (deoxyribonucleic acid) which is present inside every cell making up that organism. A chromosome is a single chain of DNA that is coiled and super coiled to form dense thread-like pieces. The term chromosome is derived from the Greek words "chroma" or color and "some" or body and is so named because chromosomes have the ability to be stained with dyes.
