Thanks for the ping. Very interesting. Especially that the RNA molecule moves up the DNA molecule with enough strength to pull the glass beads together. I wonder where that strength comes from, and whether the RNA molecule moves in ripples like an inch-worm.
Also, I wonder what happens if the free end of the RNA molecule encounters the middle of a DNA molecule. Does it start from the middle and replicate both ways, or does it first move to the end of the DNA molecule and start replicating from there?
The DNA dependent RNA polymerase starts at a unique place on one DNA strand and goes only in one direction.
