Which of the following is a characteristic of the sugar in RNA?
It is a four-carbon sugar
It is a six-carbon sugar
It contains a hydroxyl group on the 2' carbon
It contains a methyl group on the 2' carbon
RNA contains the sugar ribose, which is a five-carbon sugar with a hydroxyl group (-OH) attached to the 2' carbon. In contrast, DNA contains the sugar deoxyribose, which lacks the hydroxyl group on the 2' carbon. The presence of the hydroxyl group on the 2' carbon in RNA can affect its stability and reactivity compared to DNA. Hence option 3 is the correct answer.
Option(1) RNA contains the sugar ribose, which is a five-carbon sugar with a hydroxyl group (-OH) attached to the 2' carbon. Hence option 1 is incorrect.
Option(2) RNA contains the sugar ribose, which is a five-carbon sugar with a hydroxyl group (-OH) attached to the 2' carbon. Hence option 2 is incorrect.
Option(4) RNA contains the sugar ribose, which is a five-carbon sugar with a hydroxyl group (-OH) attached to the 2' carbon. Hence option 4 is incorrect.
