Question

multiple choice question
name the level of protein structure that is determined by the amino acid sequence of the protein.
primary
tertiary
quaternary
secondary

Explanation:

The primary structure of a protein is defined by the linear sequence of amino - acids. Secondary structure involves local folding patterns like alpha - helices and beta - sheets. Tertiary structure is the overall 3 - D shape of a single polypeptide chain. Quaternary structure is the arrangement of multiple polypeptide chains in a multi - subunit protein.

Answer:

Primary
