DNA replication is

1. conservative and discontinuous
2. semiconservative and semi discontinuous
3. semiconservative and discontinuous
4. conservative

Correct answer: semiconservative and discontinuous

Solution

DNA replication is semiconservative because each daughter DNA molecule contains one parental strand and one newly synthesized strand. It is discontinuous on the lagging strand because DNA polymerase can only synthesize in the 5' to 3' direction, producing Okazaki fragments.
