PCR is a very sensitive technique that requires small amounts of DNA (as little as 1-2 molecules of DNA), which are amplified and copied over a billion times. Earlier bulk studies of T7 helicase found that although T7 helicase is capable of ATP hydrolysis, it did not unwind DNA efficiently in the presence of ATP (Hingorani & Patel, 1996; Matson & Richardson, 1983 ). Chain-termination PCR works just like standard PCR, but with one major difference: the addition of modified nucleotides (dNTPs) called dideoxyribonucleotides (ddNTPs). Both batches produced identical PCR products of 2 kb whether freeze-thawed 5 times or freeze-thawed 20 times. I hope so you don't require calculations. DNA (200 ng of total genomic DNA, correspondingly less if cDNA is used) and primers (100 nM), each in 20 μl, are mixed, denatured at 100°, and held at 84° for 5 min. .
