Question

Which structure of protein is amino acid sequence. D is quaternary

Answer 1

Primary, so the first option, or option A

Answer 2

The correct answer is - Primary structure.

Proteins are macromolecules made of amino acids. Thus, amino acids are units of a protein. The simplest level of protein structure is the primary structure. In primary structure, amino acids are linked in a sequence by peptide bonds. The amino group of one amino acid and the carboxyl group of another amino acid is linked to form a dipeptide and many amino acids linked in a sequence to form polypeptide, the primary structure of a protein.
