Here's a breakdown:
* DNA: The molecule that carries genetic instructions in all living organisms.
* Gene: A specific segment of DNA that contains the code for a particular protein.
* Protein: A large, complex molecule made up of amino acids. Proteins perform a wide range of functions in the body, such as building and repairing tissues, transporting molecules, and fighting off infections.
The process of translating the genetic code from DNA into a protein is called gene expression.
