Review of DNA Replication and also the steps for the Cell Cycle and Mitosis p. 150 - 159 in text

Today we reviewed the steps for DNA replication:
1.  Unzip DNA strand with Helicase, which will break the hydrogen bonds
2.  Lay down RNA primer with RNA primase
3. Make the new strand with DNA Polymerase
4.  Repair the phosphodiester links with Ligase.

Today:
We took notes on cell divisioncell cycle (four stages), chromatin, chromatid, chromosome 
and diploid number:  Homework, review the vocal words above.
