A chromosome is a tightly coiled structure composed of a DNA molecule.

Explanation: chromosomes are DNA (wrapped around proteins called histones) condensed into a compact form and contain many genes. They are located in the nucleus of eukaryotic cells (prokaryotes have a circular chromosome in the nucleoid, not a nucleus).
