Human genome

The human genome is the genome of Homo sapiens, which is stored on 24 distinct chromosomes (22 autosomal + X + Y) containing an estimated 20,000–25,000 genes.The entire human genome occupies a total of just over 3 billion DNA base pairs, and has a data size of approximately 750 Megabytes. which is slightly larger than the capacity of a standard Compact Disc.
The Human Genome Project has produced a reference sequence of the euchromatic human genome, which is used worldwide in biomedical sciences. The human genome had fewer genes than expected, with only about 1.5% coding for proteins, and the rest comprised by RNA genes, regulatory sequences, introns and controversially so-called junk DNA
