Question

Quizplus · Accepted Answer

Nucleotides are the monomers of DNA and RNA. They consist of a nitrogenous base, a sugar (ribose in RNA and deoxyribose in DNA), and a phosphate group. Together, they form the building blocks of nucleic acids.

Option B is incorrect because nucleotides do not normally occur in polysaccharides, which are made up of monosaccharides.

Option C is incorrect because amino acids are the building blocks of proteins, not nucleotides.

Option D is incorrect because nucleotides do contain a sugar component.

Option E is incorrect because although some amino acids contain sulfur, nucleotides do not.
