Chromosomes vary in number and shape among living organisms. In most animals and plants, chromosomes are linear and are tightly coiled around proteins and arranged in pairs within the nucleus of the cell.Mitosis describes the division of one cell into two identical daughter cells.

The unique structure of chromosomes keeps DNA tightly wrapped around spool-like proteins, called histones. Without such packaging, DNA molecules would be too long to fit inside cells. For example, if all of the DNA molecules in a single human cell were unwound from their histones and placed end-to-end, they would stretch 6 feet.

The nucleus houses the genetic material of the cell: DNA. DNA is normally found as a loosely contained structure called chromatin within the nucleus, where it is wound up and associated with a variety of histone proteins. When a cell is about to divide, the chromatin coils tightly and condenses to form chromosomes.Chromosomes and Chromatin.
