Transfer RNA (tRNA) carries amino acids to the ribosome during protein synthesis, where they are added to the growing polypeptide chain. Ribosomal RNA (rRNA) is a component of the ribosome itself, and messenger RNA (mRNA) carries the genetic information from the DNA to the ribosome. Primary mRNA transcript is the initial product of transcription that undergoes further processing to become functional mRNA. Ribozymes are RNA molecules that have catalytic activity.
