This animation is amazing! It shows molecular interactions between DNA and other molecules. http://uk.youtube.com/watch?v=4PKjF7OumYo&feature=related How do you think they were able to get the information to create this animation? The molecular interactions could be mathematically modeled I suppose, or perhaps the animation relies on some experimental testing. I’d guess it’s a bit of both, but I’d be interested to hear if anyone has an idea how it might have been done.
