Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A sugar, a phosphate group, and a nitrogen base form the building blocks of which organic compound?

A	carbohydrates
B	lipids
C	nucleic acids
D	proteins

Explanation:

Detailed explanation-1: -A nucleotide is the basic building block of nucleic acids (RNA and DNA). A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.

Detailed explanation-2: -A nucleotide consists of a sugar molecule, a nitrogenous base, and a phosphate group.

Detailed explanation-3: -Nucleotides are the building blocks of nucleic acid.

Detailed explanation-4: -A unit composed of sugar and nitrogen base linked by the glycosidic bond is nucleoside.

Detailed explanation-5: -Nucleotides are the building blocks of nucleic acids. Each nucleotide is a composite organic molecule made up of a nitrogen base, five carbon sugars and at least one phosphate group.
