Here's a breakdown:
* Gene: A segment of DNA (or RNA in some viruses) that contains the code for a specific protein or functional RNA molecule.
* Nucleotide sequence: The order of nucleotides (adenine, guanine, cytosine, and thymine) within a gene.
* Protein: A complex molecule made up of amino acids that performs a specific function in the body.
The genetic code within a gene is translated into a sequence of amino acids, which then fold into a functional protein.
