Question

the order and properties of amino acids determine the structure of a

Explanation:

Amino acids are the building blocks of proteins. The sequence (order) and properties of amino acids in a polypeptide chain determine the structure of the resulting protein. This is a fundamental concept in Biology, which is a subfield of Natural Science. Proteins have different levels of structure (primary, secondary, tertiary, quaternary) that are influenced by the amino acid sequence and their chemical properties (like polarity, charge, etc.).
