DNA REPLICATION DNA Replication: The process by which 2 identical copies of DNA are made. Occurs during Interphase of the Cell Cycle. DNA must replicate itself before a cell divides for each new cell to have the correct amount of DNA. Target: I will be able to explain the process of DNA Replication. Pg. 99

Process of DNA Replication 1. The enzyme Helicase unwinds the DNA.  This starts at a fixed point.

2. DNA nucleotides bond to complimentary bases (A, T, C, G)on each side of the DNA.

3. DNA Polymerase joins the nucleotides in a 5’ to 3’ direction on each strand.

4. DNA Polymerase proofreads the bases and fixes any mistakes.

When DNA replication is complete, you have two identical copies of DNA. DNA Replication Summary:

-ase

STAGE OF DNA REPLICATION Pg. 98 Step 4 Step 2 Step 1 Step 3 Underneath each square, explain what is happening in each stage of DNA replication. On the notebook paper beneath the square, draw a picture to represent the 4 stages of DNA Replication. Use a minimum of 4 colors and good grammar.
