Types of RNA


RNA functions to transfer genetic instructions from the nucleus to the cytoplasm, where the information is decoded

There are three types of RNA which cooperate to complete this goal:

  • Messenger RNA (mRNA) – a transcript copy of a gene which encodes a specific polypeptide
  • Transfer RNA (tRNA) – carries the polypeptide subunits (amino acids) to the organelle responsible for synthesis (ribosome)
  • Ribosomal RNA (rRNA) – a primary component of the ribosome and is responsible for its catalytic activity
