Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The steps of PCR are as follows:
1. Denaturation: Heat the double-stranded DNA to separate it into single strands.
2. Annealing: Lower the temperature to allow primers to bind to complementary sequences.
3. Extension: DNA polymerase extends the primers by synthesizing a new strand of DNA.
4. Cycling: These steps are repeated multiple times to amplify the target DNA sequence.
