@ Melissa (and others who might be interested)

As far as I understand the mechanism they are talking about, it seems to be working without an actual “power source” such as ATP.

The DNA is “walking” because the system it is in, is naturally trying to reach a lower level of energy (just like in chemistry, where water and oil “likes” to be seperated instead of mixed).

This is done by creating a larger and larger amount of DNA-DNA bindings. When two strands of DNA are bound togeather, they are in a lower state of energy, compared to two similar single stranded DNA – hence why all DNA in our cells are normally double stranded.

I guess they are making each step (T1-T4) able to create more and more DNA-DNA bindings, and therefore it wil “walk” down the steps as it goes towards a lower state of energy.

This will make Ray Kurtzwiel happy, I’m sure.

This is really neat. I’d like to know the mechanics behind how it’s able to move. Where does ATP cleavage come in?
