Recall that nucleotides, the building blocks of nucleic acids, consist of three components: a nitrogenous base, a phosphate group, and a pentose sugar.
Understand that the pentose sugar differs between DNA and RNA, which is a key factor distinguishing these two types of nucleic acids.
Identify that in DNA, the pentose sugar is 2-deoxyribose, which lacks an oxygen atom on the 2' carbon compared to ribose.
Recognize that in RNA, the pentose sugar is ribose, which has a hydroxyl group (-OH) attached to the 2' carbon.
Therefore, the pentose sugar found in the nucleotide backbone of RNA is ribose.
