The ____ structure of a protein is the sequence of its amino acids.
A
primary
B
secondary
C
tertiary
D
quartenary
Explanation: 

Detailed explanation-1: -To reiterate, the primary structure of a protein is defined as the sequence of amino acids linked together to form a polypeptide chain. Each amino acid is linked to the next amino acid through peptide bonds created during the protein biosynthesis process.

Detailed explanation-2: -The primary sequence of a protein is the order of the amino acids in the polypeptide chain. The primary structure is coded for in the DNA of organisms and can be read through protein synthesis. During protein synthesis, DNA is copied to messenger RNA (mRNA).

Detailed explanation-3: -Answer and Explanation: The sequence of amino acids in a protein is the primary structure. There are four levels of structure to a protein that determines its final form, primary, secondary, tertiary, and quaternary. Primary structure refers to the sequence of amino acids in a protein.
