Question

Which element is found in nucleic acids but not in proteins?

carbon
hydrogen
nitrogen
phosphorus

Answer 1

Your answer is phosphorus

Answer 2

phosphorus is found in nucleic acids but not in proteins

Step-by-step explanation:

Carbon, hydrogen and oxygen (C, H, O) participate in the composition of organic compounds such as carbohydrates, lipids, proteins and nucleic acids.

Nucleic acids are formed by: carbon (C), hydrogen (H), oxygen (O), nitrogen (N) and phosphorus (P).

Proteins are biomolecules. 5 elements are found in most proteins: carbon (53%), hydrogen (7%), oxygen (23%), nitrogen (16%) and sulfur (1%). Nitrogen differentiates proteins from fats and carbohydrates.

Then we can see that phosphorus is found in nucleic acids but not in proteins
