a lot of that stuff is exaggerated. I saw a similar animation a while ago and wondered what is was based on, as observing motion on that atomic level of is quite difficult
it turned out there were a few odd proteins that slide down the chromosome for a short while, one that metabolises lactose I think, but most just bump around in the goo until they randomly hit a match, and even the ones that hang on do let go quite often. It looks in the animation that the polymerase is getting dragged by its own appendage, but they think it's the unwinding then rewinding of the chromosome itself that gives the chemical/mechanical energy to move the transcipter along. One interesting thing for coders is that the polymerase transcriber has evolved a rudimentary error detection system, and can recognise(quite rare) bad RNA it's created, will chemically tag it as such, then back itself up one base pair and do the reaction again. not bad for a molecule a few hundred atoms in length

Of course it is exaggerated, it is to illustrate processes.
The reality of rapidly moving molecules wouldn't show anything but a blur.
The colours are wrong too.

oh I accept it's always going to be a representation
it was more how close the animators were to current scientific thinking on the physical way the processes operate in the transcription phase, given that it's quite difficult to observe. i have a layman's interest in the subject, as I'm fascinated how evolution solved these problems with essentially nested levels of coding using the shape as well as the atomic components of organic molecules. That and asian ass sluts. It's good not to confine yourself to one interest
