chromosome

This term describes the physical vehicle of heredity. It evokes an image of tightly coiled biological blueprints that determine the biological traits of an organism. In a laboratory setting, the word refers to the visible structures that appear during cell division. While often used interchangeably with DNA in casual conversation, the word specifically denotes the organized package of that DNA. It carries a clinical, scientific connotation and is rarely used outside of biological, medical, or forensic contexts.
