      A DNA polymerase Correct Answer Incorrect Answer
      B Reverse transcriptase Correct Answer Incorrect Answer
      C Pol I Correct Answer Incorrect Answer
      D Protease Correct Answer Incorrect Answer

      Solution

      Reverse transcriptase (RT) is a DNA polymerase enzyme that converts single-stranded RNA to DNA. It is also known as RNA-dependent DNA polymerase. After the RNA has been reverse transcribed into single-strand DNA in the first stage, this enzyme can create a double helix DNA.
