'''ribonucleic acid''' or ''RNA''' is a molecule which is one of the carriers of genetic information in nearly all the living organisms. It contains the biological instructions for the development, survival and reproduction of organisms. | '''ribonucleic acid''' or ''RNA''' is a molecule which is one of the carriers of genetic information in nearly all the living organisms.

The expression of genes into proteins and is a process involving two stages called transcription and translation. In the transcription stage a strand of DNA molecule serves as a template for the synthesis of an [[RNA]] molecule called messenger RNA. | The expression of genes into proteins and is a process involving two stages called transcription and translation. In the transcription stage a strand of DNA molecule serves as a template for the synthesis of an [[RNA]] molecule called messenger RNA. In the case of RNAs that code for polypetides, this messenger [[RNA]] is then translated into proteins on [[Ribosome|ribosomes]]. | ||
Post-transcriptionally, specific nucleotides in RNA are often further modified. This is most frequent in [tRNA|transfer ribonucleic acid (tRNAs)]], the adapter molecules of [[Translation]], and ribosomal ribonucleic acids (rRNAs) of the [[Ribosome|ribosome]]. | |||
