Chromosome 20
Chromosome 20 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 20 spans around 63 million base pairs (the building material of DNA) and represents between 2 and 2.5 percent of the total DNA in cells.
Structure[edit | edit source]
Chromosome 20 has a large arm (q) and a small arm (p). The p arm is made up of two regions: the centromere, which is the point of attachment for the spindle fibers during cell division, and the telomere, which is the end of the chromosome.
Genes[edit | edit source]
Chromosome 20 contains about 700 to 800 genes. Some of these genes are involved in the immune system, while others are involved in the development of the brain and the nervous system.
Diseases and disorders[edit | edit source]
