What is the ultimate product of a gene?

Explanation:
Genes contain the instructions for making molecules that perform cellular work. In most cases, those instructions are first transcribed into messenger RNA and then translated into a polypeptide that folds into a functional protein. Proteins are the workhorses of the cell—enzymes, structural components, transport molecules, and signaling players—so they’re the typical ultimate product of a gene. There are some genes that code for RNA molecules with direct roles, but the common focus in introductory biology is that the final product is a protein. This reflects how information flows from DNA to RNA to protein.
