RNA, or ribonucleic acid, is a macromolecule formed by polymerizing nucleotide triphosphate (NTPs) molecules. RNA results from transcription from a DNA source. mRNA is a subclass of transcribed RNA that serves as a transient message that will be translated into protein. tRNA is a transfer RNA that carries the amino acids in the translation process. rRNA is ribosomal RNA that forms part of the large ribosomal enzyme complex that facilitates the polymerization of amino acids to protein during translation. RNA can also serve as genetic information as seen in RNA viruses.
