Step 1I'll solve this problem by breaking down the Polymerase Chain Reaction (PCR) steps with precise details:
Step 2: Denaturation
- Temperature: $$94-96^{\circ}C
- Purpose: Separate double-stranded DNA into single strands - Process: High heat breaks hydrogen bonds between DNA base pairs - Result: DNA molecules become single-stranded, allowing primers to access template
Final Answer
1. Denaturation (94 - 96^{\circ}C) 2. Annealing (50 - 65^{\circ}C) 3. Extension (72^{\circ}C)
