The term 'PASSED ON BY DNA' can be summarized by the crossword solution 'GENETIC'. This refers to the process of GENETIC inheritance, which is the passing on of traits from parent to offspring through DNA. DNA is a molecule that contains GENETIC information and is passed on from generation to generation. It is responsible for the physical characteristics of an organism, such as eye color, hair color, and height. Through GENETIC inheritance, these traits are passed on from one generation to the next.
