Denaturation annealing and elongation

WebPolymerase chain reaction (PCR) is a molecular biology technique used to amplify specific DNA segments by several orders of magnitude. The specific segments of DNA is amplified over three processes, denaturation, annealing and extension – where the DNA strands are separated by raising the temperature to the optimal from room temperature before … WebDenaturation: The reaction temperature is increased to 95 °C, which melts (disrupts the hydrogen bonds between complementary bases) all dsDNA into single-stranded DNA …
