  3. enzyme similar to DNA polymerase that binds to DNA and separates the DNA strands during transcription
  4. sequence of DNA that is not involved in coding for a protein, sequence of a eukaryotic gene's DNA that is not translated into a protein
  5. theory that states that, in cells, information only flows from DNA to RNA to proteins
