2.  Know the structure of DNA.  Be able to label DNA or draw a model on the test.

Be able to identify the 3' and the 5' ends

3.  Describe the process of DNA replication.  Know the players involved:  DNA helicase, DNA polymerase, replication fork, leading strand, lagging strand, Okazaki fragments, DNA ligase, complimentary strand, base-pairing

4. Describe the process of transcription, including where it occurs and what components are necessary for it to occur.
