Understand the structure of RNA molecules: RNA (ribonucleic acid) is a nucleic acid composed of nucleotides, each consisting of a phosphate group, a nitrogenous base, and a sugar molecule.
Identify the sugar molecule in RNA: The sugar in RNA is a pentose sugar, meaning it has five carbon atoms.
Compare the options provided: Fructose is a hexose sugar (six carbons), glucose is also a hexose sugar, and deoxyribose is the sugar found in DNA, not RNA.
Recognize the unique sugar in RNA: Ribose is the correct sugar found in RNA. It differs from deoxyribose by having a hydroxyl (-OH) group attached to the 2' carbon, which is absent in deoxyribose.
Conclude that ribose is the sugar forming the backbone of RNA molecules, as it is specifically designed to support RNA's structure and function.
