Which change to one of the kits would make it useful for modeling proteins? a. Set 1, add a box for phosphorous (P) atoms. b. Set 2, add a box for sulfur (S) atoms c. Set 3, replace the box of phosphorous (P) atoms with a box of sulfur (S) atoms d. Set 4, replace the box of oxygen (O) atoms with a box of nitrogen atoms (N)

The correct answer is - option C.

Explanation:

Proteins are made up of long chains of polypeptide chains made up of amino acids contain the basic elements of organic matter carbon, oxygen, and hydrogen with the addition of nitrogen.

In the given option set 1, and set 2 lacks the nitrogen elements whereas in set 4 the oxygen is not available, and set 3 have all the elements required for the protein.
