A group of DNA nucleotides that contains the information to produce a single protein is called a gene.

Here's a breakdown:

* DNA: Deoxyribonucleic acid, the molecule that carries genetic instructions.

* Nucleotides: The building blocks of DNA, composed of a sugar, a phosphate group, and a nitrogenous base (adenine, guanine, cytosine, or thymine).

* Gene: A segment of DNA that provides instructions for building a specific protein. This protein can then perform a specific function in the body.
