The sequence of amino acids in a protein is referred to as its primary structure is called

True

Explanation:

The proteins are the macromolecules composed of the amino acids. The amino acids are joined together by a bond called the peptide bond.

The proteins are formed by the translation process which translates the mRNA into the amino acids and when these amino acids bond they form a linear structure of the proteins.

The linear arrangement of amino acids is known as the primary structure of the protein as this linear structure undergoes further structural conformations.

Thus, true is correct.
