Number Of Genes in Human Genome

How many genes are there in human genome?

23,000

The haploid human genome contains ca. 23,000 protein-coding genes, far fewer than had been expected before its sequencing. In fact, only about 1.5% of the genome codes for proteins, while the rest consists of non-coding RNA genes, regulatory sequences, introns, and (controversially named) “junk” DNA.

This fact is verified on : December 11, 2009.
