To solve this problem, we need to identify the sugar components present in RNA and DNA.$\newline$RNA and DNA are nucleic acids that differ in their sugar components.$\newline$Let's analyze each option:$\newline$• Option 1: The sugar component in RNA is arabinose and the sugar component in DNA is 2'-deoxyribose.$\newline$• Option 2: The sugar component in RNA is ribose and the sugar component in DNA is 2'-deoxyribose.$\newline$• Option 3: The sugar component in RNA is arabinose and the sugar component in DNA is ribose.$\newline$• Option 4: The sugar component in RNA is 2'-deoxyribose and the sugar component in DNA is arabinose.$\newline$Explanation:$\newline$• RNA contains ribose as its sugar component. Ribose is a five-carbon sugar with a hydroxyl group (-OH) on the 2' carbon.$\newline$• DNA contains 2'-deoxyribose as its sugar component. 2'-deoxyribose is similar to ribose but lacks the hydroxyl group on the 2' carbon, having only a hydrogen atom instead.$\newline$Therefore, the correct statement is:$\newline$• The sugar component in RNA is ribose and the sugar component in DNA is 2'-deoxyribose.$\newline$This corresponds to Option 2.
