2. The test on Meiosis (Ch. 13), DNA Structure (Ch. 16.1) and DNA Replication (Ch. 16.2) is still on Tuesday.
3. Remember that on Wednesday we have a wonky schedule with 39 minute classes.
Today in class we started with a warm up to review basic DNA structure.
We then spent a little time clarifying expectations on the DNA replication model.
Finally we began our discussion of DNA Replication. We looked at the experiments of Meselson and Stahl which confirmed that DNA replication is semi-conservative, that is, the two strands of DNA separate and then are used as templates for complementary strands. You can review this experiment here or here.
We will be examining the details of DNA replication together on Monday. To prepare for our conversation here are some animations:
McGraw-Hill
Wiley
HHMI BioInteractive
Coordination of Leading and Lagging Strand
Movie of the process
See you Monday!
