Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).\n Assertion (A): During PCR, primers are oriented such that the DNA polymerase extends them towards each other across the target sequence.\n Reason (R): DNA polymerases can synthesize new strands only in the 5' to 3' direction. \nIn the light of the above statements, choose the correct answer from the options given below:

  1. Both (A) and (R) are true and (R) is the correct explanation of (A).
  2. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
  3. is true but (R) is false.
  4. is false but (R) is true.

Correct answer · Option 1

Both (A) and (R) are true and (R) is the correct explanation of (A).

Explanation

Because DNA polymerases add dNTPs exclusively to the free 3'-OH group (5' to 3' direction), primers anneal to opposite strands at opposite ends directed towards each other.
