Which enzyme is essential for performing PCR when the starting material is messenger RNA (mRNA)?

  1. Taq polymerase
  2. Reverse transcriptase
  3. DNA ligase
  4. Eukaryotic RNA polymerase II
Show answer and explanation

Correct answer: Reverse transcriptase

Reverse transcriptase is used in RT-PCR to convert RNA into complementary DNA (cDNA). Once the cDNA is synthesized, it can be used as a template for standard PCR amplification.
