Guida verificata passo dopo passo1
Understand that nucleotides, the building blocks of nucleic acids like RNA and DNA, consist of three components: a nitrogenous base, a phosphate group, and a sugar molecule.
Recall that the sugar in the nucleotide backbone differs between RNA and DNA, which is a key factor in their structural and functional differences.
Identify that DNA contains the sugar deoxyribose, which lacks one oxygen atom compared to the sugar found in RNA.
Recognize that RNA contains the sugar ribose, which has a hydroxyl group (-OH) attached to the 2' carbon of the sugar ring, distinguishing it from deoxyribose.
Conclude that the sugar found in the nucleotide backbone of RNA is ribose, not glucose, fructose, or deoxyribose.
