The closed captions on that last video are pretty a-ok:

That's nothing. If you want to see something even more unbelievable, look at what happens when it is unfolded for replication:

There is some pretty amazing stuff going on in the cell outside the DNA, too. To move stuff through the cell there are a series of things called microtubule. Think of them as like catwalks connecting various regions. To move things through the cell things called "motor proteins" are used. These are long proteins that attach at one end to thing to be moved, and (I'm not kidding) have a couple little feet at the other end that they use to walk along the microtubule towing their cargo.
Here's an animation of one walking:

Here is an explanation of how the hell it does that chemically:
