What is the primary functional distinction between DNA and RNA?

Show Answers

RNA has ribose sugar in its structureDNA stores genetic information in all living organismsDNA is found mainly within the cell nucleusRNA lacks the base thymineRNA is double-stranded

Explanation

Option A is true that RNA contains ribose, but the key functional difference is that DNA holds the genetic blueprint for all living organisms, which is why option B is correct. Options C and D describe structural differences, not functional roles.
