Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which elements make up nucleic acids?
A
Carbon, Hydrogen, Oxygen
B
Carbon, Hydrogen, Oxygen, Nitrogen
C
Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorous
D
None of the above
Explanation: 

Detailed explanation-1: -Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P). Nucleic acids are very large macromolecules composed of repetitive units of the same building blocks, nucleotides, similar to a pearl necklace made of many pearls.

Detailed explanation-2: -Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON). Nucleic acids such as DNA and RNA contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON P).

Detailed explanation-3: -Five Easy Pieces All nucleic acids are made up of the same building blocks (monomers). Chemists call the monomers “nucleotides.” The five pieces are uracil, cytosine, thymine, adenine, and guanine.

Detailed explanation-4: -Proteins are made of carbon, hydrogen, oxygen, nitrogen, & sometimes sulfur (CHONS). Nucleic acids contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHONP).
