Genome

Definition

The complete set of genetic material in an organism, including all genes and non-coding DNA sequences.

Detailed Explanation

Genome size varies enormously across life and does not correlate with organismal complexity — the marbled lungfish has a genome 40 times larger than a human's. The Human Genome Project, completed in 2003, transformed biology by revealing gene number, regulatory regions, and evolutionary relationships. Whole-genome sequencing now costs under $1,000, enabling population-scale genomics for conservation, medicine, and evolutionary research.
