Recall that nucleotides, the building blocks of nucleic acids like RNA and DNA, consist of three components: a nitrogenous base, a phosphate group, and a five-carbon sugar.
Understand that the sugar component differs between RNA and DNA, which is a key factor in their structural and functional differences.
Identify that in RNA, the sugar is a ribose sugar, which has a hydroxyl group (-OH) attached to the 2' carbon atom.
Contrast this with DNA, where the sugar is deoxyribose, which lacks the hydroxyl group at the 2' carbon, having only a hydrogen atom instead.
Therefore, the five-carbon sugar in the nucleotide backbone of RNA is called ribose.
