Answer
A genome is the complete set of genetic information (all DNA) in an organism all genes and non-coding sequences.
- Human genome: ~3 billion base pairs and ~20,000–25,000 genes.
- Every cell (except red blood cells) contains the complete genome.
- Human Genome Project (completed 2003) sequenced the entire human genome.
- Includes both coding DNA (genes) and large amounts of non coding DNA.
A genome is an organism's complete DNA blueprint every gene and sequence it possesses, contained in every cell.
