Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A nucleic acid is made up of which of the following elements?
A
hydrogen
B
phosphorus
C
oxygen
D
nitrogen
E
carbon
Explanation: 

Detailed explanation-1: -Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P).

Detailed explanation-2: -Nucleic acids are one of four classes of biochemical compounds. (The other three classes are carbohydrates, proteins, and lipids.) Nucleic acids include RNA (ribonucleic acid) as well as DNA (deoxyribonucleic acid). Both types of nucleic acids contain the elements carbon, hydrogen, oxygen, nitrogen, and phosphorus.

Detailed explanation-3: -A single basic unit or “building block” of DNA consists of a sugar, a phosphate group and a base. Sugars are rings of carbon and oxygen atoms. The sugar in DNA has 5 carbon atoms (labelled 1’-5’), and is called deoxy-ribose (hence the “Deoxy-ribo” in DNA).

Detailed explanation-4: -Nucleic acids are made of carbon, hydrogen, oxygen, nitrogen and phosphorous atoms. Nucleic acids store and transfer cellular information and transfer energy in all living organisms. Nucleic acids are made of small repeating units or building blocks called nucleotides.
