Human Genome
The human genome is the genome of Homo sapiens, which is stored on 24 distinct chromosomes. Twenty-two of these are autosomal chromosomes, while the remaining two (X and Y) are sex-determining. The entire human genome occupies a total of just over 3 billion DNA base pairs and has a data size of approximately 750 Megabytes[1], which is slightly larger than the capacity of a standard Compact Disc. The Human Genome Project produced a reference sequence of the euchromatic human genome, which is used worldwide in biomedical sciences. The human genome contains an estimated 20,000–25,000 protein-coding genes, far fewer than had been expected before its sequencing.[2] In fact, only about 1.5% of the genome codes for proteins, while the rest is comprised of RNA genes, regulatory sequences, introns and (controversially) "junk" DNA.[3]
