Guida verificata passo dopo passo1
Understand that nucleotides in nucleic acids consist of three components: a nitrogenous base, a phosphate group, and a pentose sugar.
Recall that the pentose sugar in DNA is deoxyribose, which lacks one oxygen atom compared to ribose.
Recognize that RNA contains a different pentose sugar than DNA, which includes an oxygen atom on the 2' carbon.
Identify that the pentose sugar in RNA is ribose, which has a hydroxyl group (-OH) attached to the 2' carbon.
Conclude that among the options given (Ribose, Glucose, Fructose, Deoxyribose), ribose is the correct pentose sugar found in the RNA backbone.
