Question

DNA has more oxygen than RNA
Options
A True
B False
Correct Answer
C
D
Correct Answer

Option B is the correct answer.

Detailed Explanation

This statement is false. The sugar in RNA is ribose, which has an -OH group on the 2' carbon. The sugar in DNA is deoxyribose, which lacks this oxygen atom (it has just a hydrogen at the 2' position). Therefore, RNA actually has more oxygen atoms than DNA.

Hint

Which nucleic acid's sugar has an extra oxygen atom?
