Describe the features of the human genome.

The human genome consists of 23 pairs of chromosomes located in the nucleus, as well as mitochondrial DNA. Twenty-two pairs of autosomes, two sex chromosomes X and Y, as well as human mitochondrial DNA, together contain approximately 3.1 billion base pairs. The human genome contains about 30 thousand genes, which is much less than expected at the beginning of the project (about 100 thousand).
