  16. I. Why does DNA replicate? • Every new cell needs its own DNA. • Must be identical to original. • Occurs during interphase, before mitosis.

  17. II. Replication A. Step 1- The hydrogen bonds holding the base pairs together are broken and the DNA unzips into 2 separate single strands.

  18. B. Step 2 of Replication • As the DNA is unzipping, each strand becomes a template. • Free nucleotides from the cell match with the corresponding base pair. They are bonded by DNA polymerase.

  19. C. Step 3 of Replication • Replication produces 2 new single strands, each connected to one original strand. • Since one strand is “conserved” in each new molecule of DNA, this is called semi-conservative replication

  20. Summary List the steps of replication. Why is replication necessary?
