Here are the essential concepts you must grasp in order to answer the question correctly.
Nucleotides
Nucleotides are the building blocks of nucleic acids like DNA and RNA. Each nucleotide consists of a sugar, a phosphate group, and a nitrogenous base. The sugar component is crucial as it determines whether the nucleotide is part of DNA or RNA, influencing the structure and function of the nucleic acid.

Deoxyribose vs. Ribose
The primary difference between DNA and RNA sugars lies in their structure. DNA contains deoxyribose, which lacks one oxygen atom compared to ribose, the sugar found in RNA. This structural difference contributes to the stability of DNA and the reactivity of RNA, affecting their roles in genetic information storage and protein synthesis.

Function of Sugars in Nucleic Acids
The sugars in DNA and RNA play a vital role in the overall structure and function of these molecules. In DNA, deoxyribose contributes to the double-helix structure, providing stability for long-term genetic storage. In contrast, ribose in RNA allows for more flexibility, facilitating its various roles in protein synthesis and regulation within the cell.
