DNA and RNA: What is the difference?

It is the association of the different nucleotides that form the macromolecules of the two types of nucleic acids: ribonucleic acid (RNA) and deoxyribonucleic acid (DNA).

They were named after the sugar in their molecules: RNA contains ribose sugar and DNA contains deoxyribose sugar.

Another important difference between DNA and RNA molecules concerns nitrogenous bases: in DNA, the bases are cytosine, guanine, adenine and thymine; in RNA, instead of thymine, is uracil. The importance and functioning of nucleic acids.
