An idealized representation of a chromosome with an overexagerated molecule of DNA (double-helix) shown inside.
Humans have 23 pairs of chromosomes in somatic cells. The chromosome is composed of a very long DNA molecule and associated proteins (together known as chromatin). The DNA is what is generally understood as the "information molecule" that carries the hereditary information of an organism to its progeny.
