1. DNA Replication During replication, the molecule splits into two strands Each half serves as a template to make a new, whole molecule When we make a new strand, we call it the complimentary strand!

2. Step 1 DNA Helicase (an ENZYME!) “unzips” DNA down the middle

3. Step 2 New bases are laid down according to the patter on each side of the split DNA strand. The job of DNA Polymerase is to add new nucleotides to the DNA!

4. Step 3 Each new strand of DNA is “zipped” back up. You now have two strands of DNA, each containing one piece of the old DNA and one piece of the new DNA

6. Enzymes Enzyme that “unzips” DNA: (Enzyme that works on a helix) Helicase Enzyme that makes polymers of DNA (Enzyme that makes polymers) DNA Polymerase End in what 3 letters? “-ase”!
