## Definition

the complete set of genetic instructions needed to build and operate a living thing. You can think of it as the master blueprint found inside every cell of an organism.

For teachers: the entire set of genetic material, including all genes and non-coding sequences, contained within a cell or organism.

## Examples

- Scientists mapped the human genome to understand our DNA better.
- By sequencing the plant's genome, researchers identified the specific genes responsible for its resistance to drought.
- Advances in high-throughput sequencing have allowed biologists to compare the genomes of different species, revealing deep evolutionary connections that were previously hidden from view.

## Usage notes

- Often used with the definite article ('the genome') when referring to a species as a whole.
