While watching this Molecular Visualizations of DNA it struck me how much the motion resembles Conway's Game of Life. And not only visually; each molecule/atom is described by a finite set of interaction rules, right? Except they are probabilistic, not deterministic.

How complete is our understanding of the DNA molecular motors and has their movement been fully calculated?

What exactly do you mean by "DNA molecular motors"? There are several different enzymes involved in what you see in the video you linked. –  Mad Scientist Feb 28 at 12:00
    
From my googling I understood that all(most) of those enzymes in this video are called DNA molecular motors but if you wan't to be specific let's discuss the Helicase. –  daniel.sedlacek Feb 28 at 12:05
    
What do you mean by "has their movement been fully calculated"? How helicases work is understood, yes. –  Chris Feb 28 at 12:22

You may want to examine the work of scientists like Carlos Bustamante, Steve Block, and other Single Molecule Biophysicists. The main thrust of their research has been in characterizing the motion and mechanics of molecular motors moving along DNA. –  A. Kennard Mar 1 at 12:36
    
Most biophysical experiments are done invitro and there is some fair idea about the mechanics as inferred by these experiments. How complete? I guess we are quite far from being complete.. –  WYSIWYG Mar 3 at 3:50
