Answer: The correct answer is-
This sugar is ribose in RNA and deoxyribose in DNA.
Nucleic acid is one of the four major macromolecules that are essential for the living organisms. It includes DNA ( deoxyribonucleic acid) and RNA ( ribonucleic acid).
It is composed of small units called nucleotides, which are made up of three components-
Pentose sugar that is 5 carbon containing sugar ( which is ribose in case of RNA and deoxyribose in DNA), nitrogenous base ( A,T,G,C in DNA and A,U,G,C in RNA) and a phosphate group.
