Answer:
1) Proteins consist of the elements carbon, hydrogen, oxygen, nitrogen, and sulfur. Whereas nucleic acids are Nitrogen (N), Oxygen (O), Carbon ( C), Phosphorous (P), and Hydrogen (H)
2) Nucleic acid monomers are called nucleotides; protein monomers are called amino acids.
Explanation: Proteins are one of the primary constituents of living matter. They consist of long chains of amino acids, which are bonded together by peptide linkages and are thus called polypeptides. There are about 20 amino acids, and the atoms most prevalent in these are carbon, hydrogen, oxygen, nitrogen, and sulfur.
Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P). Carbon, hydrogen, oxygen, nitrogen, and phosphorous act as the building blocks for nucleic acids. and the five elements necessary to construct a nucleic acid chain are carbon, hydrogen, oxygen, nitrogen, and phosphorus.
