‘‘It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material’’ (Watson and Crick, 1953). What will be true regarding he statement quoted?
I: The ‘specific pairing’ refers to complementary base pairing.
II: The ‘possible copying mechanism’ refers to conservative mechanism of DNA replication.

During DNA replication, the proofreading activity of DNA polymerase ensures high fidelity of the newly synthesized strand. This proofreading function is due to the:

1. 5' to 3' polymerase activity
2. 3' to 5' exonuclease activity
3. 5' to 3' exonuclease activity
4. Helicase activity
