REPLICATION Organize the steps of DNA replication...
1. Two new copies of DNA are created, each containing one strand from the original DNA molecule.
2. DNA Polymerase joins complementary nucleotides to the template strands.
3. DNA Helicase "unzips" DNA breaking bonds between the 2 template strands.
4. The newly created strands are "proof-read" for errors.
5. DNA Polymerase attaches to each exposed template strand.
