WebHeating to 90-95 ∘C denatures the double-stranded DNA so that it dissociates into single strands. In a typical PCR reaction, describe what is happening in stages occurring at temperature ranges: 50-70 ∘C Lowering the temperature to 50-70 ∘C allows the primers to bind to the denatured DNA. WebInitially, the DNA template is denatured by heating it to a high temperature, causing the double-stranded DNA to separate into two single strands. Then, small DNA primers are annealed to the target DNA sequence, allowing a heat-stable DNA polymerase enzyme to stretch from the primer and manufacture new DNA strands complementary to the template. reading audit logs

WebPCR involves a process of heating and cooling called thermal cycling which is carried out by machine. There are three main stages: Denaturing – when the double-stranded template DNA is heated to separate it into two single strands. Annealing – when the temperature is lowered to enable the DNA primers to attach to the template DNA.
