Where is most of the body's DNA stored?
Quick Answer
Most human DNA is stored in the cell nucleus, packaged into 23 pairs of chromosomes. A small amount is also found in mitochondria.
The Full Story
In humans, the vast majority of DNA is located in the cell nucleus, where it is organized into 46 chromosomes, or 23 pairs. This nuclear DNA contains the genes that shape most inherited traits and direct the body's development and function. A much smaller genome is found in mitochondria, the cell's energy-producing structures, which have their own circular DNA. Mitochondrial DNA is inherited almost entirely from the mother in humans.
Key Facts
1.Humans have 23 pairs of nuclear chromosomes
2.Mitochondria contain a small separate genome
3.Mitochondrial DNA is typically maternally inherited
