The shape of a protein is most directly determined by the
amount of energy available for synthesis of the protein
kind and sequence of amino acids in the protein
type and number of DNA molecules in a cell
mistakes made when the DNA is copied
Answer and Explanation:
Proteins are essential molecules in our body that compose most of the tissue. Proteins are made up from amino acids (molecules that contain an amino group as well as carboxylic acid group). Proteins have primary, secondary and tertiary structures. The primary structure is the sequence of amino acids, and it determines what the shape of the proteins will be. In a famous experiment, after denaturing the protein (loosing it's shape), it was able to reshape itself correctly proving that the shape was determined by the sequence of amino acids. Therefore choice 2, kind and sequence of amino acids in the protein, is the correct answer choice.
