### Step-by-Step Solution: 1. **Role of Heat in PCR:** - Heat is crucial in the PCR process as it facilitates the denaturation of double-stranded DNA. - During PCR, the temperature is raised to approximately 95 degrees Celsius. - This high temperature causes the hydrogen bonds between the two strands of DNA to break, resulting in the separation of the double-stranded DNA into two single strands. - This step is essential for the subsequent annealing of primers. ...
