The Nuts and Bolt of DNA

Today's homework is THINKING about yesterday's class--in your lab books, DRAW the model as you remember it, and write down the significant ideas that we discussed in class, as much as you can remember.  Then PONDER the question: How does the shape of the DNA contribute to what it does? (And what actually does it do?)  How might it contain information? How does it copy itself?  Write down your ideas.
