Here's a breakdown:
* DNA (Deoxyribonucleic acid): The molecule that carries genetic instructions in all living organisms.
* Gene: A specific sequence of DNA that contains the instructions for building a particular protein or functional RNA molecule. These proteins and RNA molecules are responsible for carrying out various functions in the body, which in turn determine our traits.
* Trait: A specific characteristic of an organism, such as eye color, height, or disease susceptibility.
Example: A gene called "OCA2" codes for a protein involved in melanin production. Different versions of this gene can lead to different eye colors, such as blue, brown, or green.
