RNA Processing
  • Very few RNA molecules are transcribed directly
    into the final mature RNA.
  • Most newly transcribed RNA molecules (primary
    transcripts) undergo various alterations to yield
    the mature product
  • RNA processing is the collective term used to
    describe the molecular events allowing the
    primary transcripts to become the mature RNA.
