Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The sugar/monosaccharide found in DNA is ____
A
deoxyribose
B
ribose
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The monosaccharide deoxyribose, or more specifically 2-deoxyribose, has the idealized formula H(C=O)(CH2)(CHOH)3H. Its name denotes that it is a deoxy sugar, meaning that it is created by removing an oxygen atom from the sugar ribose. Deoxyribose is most well-known for its use in DNA.

Detailed explanation-2: -Ribose is a monosaccharide pentose sugar present in RNA while deoxyribose is a derived monosaccharide sugar present in DNA.

Detailed explanation-3: -DNA contains deoxyribose as the sugar component and RNA contains the sugar ribose.

Detailed explanation-4: -Pentose sugar for RNA is ribose with 5 carbon atoms. Pentose sugar for DNA is deoxyribose.

Detailed explanation-5: -The pentose sugar in DNA is called deoxyribose, and in RNA, the sugar is ribose. The difference between the sugars is the presence of the hydroxyl group on the 2’ carbon of the ribose and its absence on the 2’ carbon of the deoxyribose.
