A genome is an organism's complete set of genetic information. It contains all the information an organism needs to function and develop. In living organisms, the genome is stored in long DNA molecules called chromosomes. In humans, the genome consists of 23 pairs of chromosomes in the cell's nucleus and a small chromosome in the cell's mitochondria. Most genomes, including the human genome, are made of DNA (deoxyribonucleic acid). However, a few viruses have RNA (ribonucleic acid) genomes. The study of the genome is called genomics. he Human Genome Project began in 1990 and reported the... Show more
