Organized structures, formed by deoxyrubonucleic acid (DNA) and proteins, that can be found in pairs in the nucleus of cells, moments before cell division.

In humans, each cell contains 23 pairs of chromosomes, including the two chromosomes responsible for sexual characteristics (XX in women and XY in men).
