Questions for class discussion

In Class Activities

Discuss paper -

Each group should present the figures from within their section and lead discussion of the meaning and significance of the results. You may need to refer to the experimental section or past class material and lectures on fluorsecnce CD, denaturation, etc.

You have to read all sections. But you will lead the discussion of your sections. I will have the figures displayed on the overhead for you to refer to.

Each team will have 3 minutes/person to present their section(s).
