As an aside, note that the RNA polymerase, once brought into contact with the DNA strand, simply begins its replicative journey, moving along the strand one base pair at a time (as the experiment apparently demonstrates for the very first time). Now why does the RNA do this? Nobody (in their right mind) would suggest that it has a will and is acting intentionally, or that some unseen deity's hand is continually pushing it along, so it must be acting as its chemical structure compels it to act. This base-pair by base-pair copying motion must simply be what the chemical structure of RNA does. This is not written correctly at all.
You really don't know what DNA, RNA or a polymerase are, do you?

I think I made this point a little while ago, but don't beat him up too much on this, he apologized too :-)
