Which bacterial enzyme is responsible for synthesizing new DNA strands during a standard PCR cycle?
Correct answer: C. Taq DNA polymerase
- A. Reverse transcriptase
- B. RNA polymerase
- C. Taq DNA polymerase
- D. DNA ligase
Explanation
Taq DNA polymerase extends primers and synthesizes new DNA during PCR, while remaining active through repeated heating cycles. Reverse transcriptase makes DNA from RNA, RNA polymerase makes RNA, and DNA ligase joins DNA fragments.

About Veterinary Microbiology and Immunology
Covers the structure, classification, growth and transmission of bacteria, viruses, fungi and other disease causing microorganisms in animals. It explains innate and acquired immunity, antibodies, antigens, vaccination, hypersensitivity and diagnostic methods, while distinguishing infectious agents from the immune responses they produce.
