WebApr 12, 2024 · 2. Reverse transcriptase PCR (RT-PCR): RT-PCR first converts RNA to complementary DNA (cDNA) using the reverse transcriptase enzyme. The cDNA is further amplified using PCR. 3. Nested PCR: Nested PCR is a method to improve sensitivity and specificity involving two primer sets and two successive PCR reactions. WebPCR is so sensitive that DNA sequences present in an individual cell can be amplified. The isolation and amplification of a specific DNA sequence by PCR is faster and less technically difficult than traditional cloning methods using recombinant DNA techniques.
