Following are the steps involved in the process of PCR.
A. Annealing
B. Amplification (~1 billion times)
C. Denaturation
D. Treatment with Taq polymerase and deoxynucleotides
E. Extension Choose the correct sequence of steps of PCR from the options given below:
A
C → A → D → E → B
B
A → B → E → D → C
C
A → C → E → D → B
D
D → B → E → C → A
Correct Answer
