The complete set of DNA in an organism is called its genome.
A genome includes the organism’s genes and the DNA between genes. In humans, the nuclear genome is distributed across 23 chromosome types, while mitochondrial DNA forms a much smaller separate genome inside mitochondria. A genome therefore contains more than just protein-coding genes.
The word genome combines the ideas of gene and chromosome. Genome size varies enormously among organisms and does not simply predict biological complexity. Some plants, amphibians, and other organisms have genomes much larger than the human genome because of repeated or noncoding DNA.
Genome and genotype are related but different terms. A genome is the complete genetic material, whereas a genotype usually describes the particular genetic variants carried by an individual or at specific loci. The proteome is the collection of proteins produced, not the DNA itself.
