Chromosome 20 is one of the 23 pairs of chromosomes in humans. Chromosome 20 spans around 66 million base pairs (the building material of DNA) and represents between 2 and 2.5 percent of the total DNA in cells. Chromosome 20 was fully sequenced in 2001 and was reported to contain over 59 million base pairs.[4] Since then, due to sequencing improvements and fixes, the length of chromosome 20 has been updated to just over 66 million base pairs.[5]
