This COVID-19 test detects … NettetThe PCR technique is based on the enzymatic replication of DNA. In PCR, a short segment of DNA is amplified using primer mediated enzymes. DNA Polymerase synthesises new strands of DNA complementary to the template DNA. The DNA polymerase can add a nucleotide to the pre-existing 3’-OH group only. Therefore, a …
Nettet6. jan. 2024 · The steps involved in the PCR technique are as follows: A mixture is created, with optimized concentrations of the DNA template, polymerase enzyme, primers, and dNTPs. The ability to heat the mixture without denaturing the enzyme allows for denaturing of the double helix of DNA sample at temperatures in the range of 94 degrees Celsius.
