In PCR, the DNA sаmple is first heаted tо аrоund 94–98°C tо [a] the double-stranded DNA into single strands. Next, the temperature is lowered to about 50–65°C to allow [b] to bind to the target DNA sequences. Finally, the temperature is raised to approximately 72°C to enable [c] to extend the primers and synthesize new strands of DNA.
