A protein has multiple levels of structure. Which level is the most important for determining the final shape of the protein and its function?

Question

Question 5 options:

The amount of amino acids present in the secondary level of structure.

The sequence of amino acids in the primary level of structure.

The sequence of DNA nucleotides in the secondary level of structure.

The amount of amino acids present in the quaternary level of structure.

Answer 1

The most important level of structure for determining the final shape of the protein and its function is the sequence of amino acids in the primary level of structure.

The primary structure of a protein, which is the linear sequence of amino acids, dictates how the protein will fold into its secondary, tertiary, and quaternary structures, ultimately determining its shape and function. Therefore, the correct answer is:

The sequence of amino acids in the primary level of structure.
