About genes. Genes are found in the DNA in each cell that makes up your body. They control how the cell functions, including how quickly it grows, how often it divides, and how long it lives. Researchers estimate that there are 30,000 different genes in each cell. Genes are located on 46 chromosomes, which are arranged in two sets of 23 chromosomes. You inherit one set of chromosomes from your mother and one set from your father. One chromosome in each set of 23 determines whether you are female or male.
