JEE Main Chemistry question

The main point of difference between DNA and RNA is:

(A)Presence of thymine in DNA and RNA
(B)Presence of deoxyribose and thymine in DNA, ribose and uracil in RNACorrect
(C)Presence of ribose and thymine in DNA, deoxyribose and uracil in RNA
(D)Presence of deoxyribose in DNA and ribose in RNA

Answer: (B)

Solution

DNA is built from deoxyribose sugar and uses thymine as one of its pyrimidine bases, while RNA is built from ribose sugar and uses uracil in place of thymine; this combined sugar-and-base difference is the main distinguishing feature between the two nucleic acids (option d
