PCR technique was invented by__________?
Correct answer: A. Karry Mullis
- A. Karry Mullis
- B. Boyer
- C. Sanger
- D. Cohn
Explanation
Kary Mullis developed the polymerase chain reaction, which repeatedly copies a selected DNA segment through cycles of denaturation, primer binding and extension. Sanger is the likely distractor because he developed a major DNA sequencing method, not PCR.
