Verified step by step guidance1
Recall the basic structure of nucleotides, which consist of three components: a nitrogenous base, a phosphate group, and a sugar molecule.
Understand that the sugar component differs between DNA and RNA nucleotides, which is key to distinguishing them.
Identify that DNA nucleotides contain the sugar 2-deoxyribose, which lacks one oxygen atom compared to ribose.
Recognize that RNA nucleotides contain the sugar ribose, which has a hydroxyl group (-OH) attached to the 2' carbon.
Conclude that among the options given, ribose is the sugar found in RNA nucleotides.
