WebDuring a PCR, changes in temperature are used to control the activity of the polymerase and the binding of primers. To begin the reaction the temperature is raised to 95 o C. At this temperature all double stranded DNA is "melted" in to single strands: The temperature is then lowered to ~50 o C. WebTm is the melting temperature of the PCR product. Since the DNA helix melts in a temperature range rather that at one very specific temperature, Tm is defined as the temperature at which 50% of the helices are …
