Human chromosomes. Computer artwork of a pair of human chromosomes. Humans have 23 pairs of such chromosomes in their cells, making a total of 46 chromosomes. Chromosomes are a condensed form of the genetic material DNA (deoxyribonucleic acid). The DNA condenses into chromosomes during cell replication for ease of division and transport into the new cell. Each chromosome consists of two identical strands (chromatids), aligned parallel to each other and joined at an area called a centromere. The banding is formed by staining the chromosome. Each of the 46 human chromosomes can be identified by a unique banding pattern.
