Chromosomal
Chromosomal
Chromosomal (pronunciation: kroh-MO-suh-muhl) is an adjective that pertains to chromosomes, the thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA).
Etymology
The term "chromosomal" is derived from the Greek words "chroma" meaning color and "soma" meaning body. This is due to the ability of chromosomes to be stained with dyes, making them visible under a microscope.
