Do you know? The backbone of the nucleic acids to maintain their uniformity is phosphate groups and pentose. And you should note that, the pentose sugar is ribose instead of deoxyribose in RNA.

There are three types of RNA on the basis of their functions: ribosomal RNA (r-RNA), messenger RNA (m-RNA) and transfer RNA (t-RNA) which have their specific work or function.
