Quick Answer
Genes are located on chromosomes in the nucleus of cells. Some genes are also found in mitochondrial DNA.
The Full Story
In humans, genes are segments of DNA arranged along chromosomes in the nucleus. They provide instructions for making proteins and functional RNA molecules. Most genes are on the 23 pairs of nuclear chromosomes, but mitochondria also carry a small set of genes. Different gene variants, called alleles, help explain inherited traits and some diseases.
