Dna Replication

During DNA replication, Okazaki fragments are used to elongate:

1.	The lagging strand towards the replication fork.
2.	The leading strand away from the replication fork.
3.	The lagging strand away from the replication fork.
4.	The leading strand towards the replication fork.

The experimental proof for semiconservative replication of DNA was first shown in a:

1. Fungus

2. Bacterium

3. Plant

4. Virus
