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

A	Nucleotide
B	Amino acid
C	DNA
D	RNA

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: -DNA carries the heritable genetic information of the cell and is composed of two antiparallel strands of nucleotides arranged in a helical structure. Each nucleotide subunit is composed of a pentose sugar (deoxyribose), a nitrogenous base, and a phosphate group.

Detailed explanation-3: -Definition. The molecules that serve as the building blocks of DNA and RNA. Nucleotides consist of one nitrogenous base – adenine, cytosine, guanine, or thymine (uracil in RNA), a sugar (deoxyribose in DNA, ribose in RNA) and a phosphate group.

Detailed explanation-4: -The building blocks of DNA consist of three groups which are a phosphate group, a sugar group and four nitrogenous bases. These are called nucleotides.

Detailed explanation-5: -Nucleotides are the building blocks of nucleic acid. Each nucleotide consists of three parts: a sugar (ribose for RNA and deoxyribose for DNA), a phosphate, and a nitrogenous base.
