WebApr 9, 2024 · In general, a single PCR run will undergo 25-35 cycles. The first step for a single cycle is the denaturation step, in which the double-stranded DNA template molecule (Figure 2) is made single-stranded(Figure 3). The temperature for this step is typically in the range of 95-100°C, near boiling. WebPolymerase chain reaction (PCR) is a technology for exponential amplification of a fragment of DNA. (The PCR is covered by patents owned by Hoffman-La Roche. A license is required to use the PCR process.) The limit of its sensitivity is a single molecule, making PCR a superb qualitative tool for the specific detection of rare DNA sequences. higher bauer
