A nucleotide consists of which components?

Explanation:
A nucleotide is the building block of DNA and RNA and is made of three parts: a five-carbon sugar (deoxyribose in DNA or ribose in RNA), a nitrogenous base attached to that sugar, and a phosphate group attached to the sugar. The sugar and phosphate form the backbone of the nucleic acid through phosphodiester bonds, while the base provides the genetic information through specific pairing (A with T or U, and G with C). Because a nucleotide must include all three components, any option that lists only two parts misses something essential. So, sugar, base, and phosphate group together define a nucleotide.
