    I like all the answers, even the funny one!

    In general what is nice about models is that they allow a concrete visualization of something. And then that allows you to create/see new connections and things that you could miss by just waving your hands around to describe it. In specific terms it allows you to say, for example, "If this model is correct, then it should also be true then, that there is a major groove and a minor groove in the DNA. How can we test that idea to see if it is true". In other words does the test prove or disprove something seen or described in the model. The model gives you ideas and ways to test the model to see how good a model it really is.

    On the other hand, models have limitations. The behavior of atoms and molecules is not exactly what you see in a physical model, so you could miss something if you fail to keep in mind that the real thing is very much more complicated than a physical model.

    Most physical three dimensional models would be limited in describing the complexities of DNA sequencing. It's an essential part of the DNA story that would require quite a bit of interaction between the audience and the model.

    Limitations: Detail (we will never know what it REALLY looks like, only what people draw up) Ever seen an atom on a Electron Microscope? it looks like just a little bump. Hard to believe they got that detailed diagram from one of those pictures.

    Advantage: Understanding, visualizations.

    don't think many models would kow about DNA's structure...at least not the ones i've met.
