## Definition

a tiny structure inside your cells that carries your genetic information. Think of it as a package that holds the instructions for how your body grows and works.

For teachers: a thread-like structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.

## Examples

- Humans have 23 pairs of chromosomes in their cells.
- Doctors tested the baby's chromosomes to check for any genetic conditions.
- During cell division, chromosomes condense and become visible under a microscope, ensuring that each new cell receives an identical set of genetic instructions.
