I would like to understand how cellular biology processes actually work. Like, how do all the right modules and proteins line up in the right orientation every time? Every time I watch animations, it seems like the proteins and such just magically appear when needed and disappear when not needed [0]. Sometimes it's an ultra-complex looking protein and it just magically flys over to the DNA, attaches to the correct spot, does it's thing, detaches, and flies away. Yeah right! As if the protein is being flown by a pilot. How does it really work?

A friend of mine showed me this writeup when I asked a similar question, and it helps to clear up a lot of the "magic" movement:

But in a nutshell, the animations are heavily idealized, showing the process when it succeeds, slowing it way, way down, and totally ignoring 90% of the other nearby material so you can see what's going on. Then you remember that you have just a bajillion of cells within you, all containing this incredibly complex machinery and... it's really kindof humbling just how little we actually know about any of it. Not to discredit the biologists and scientists for whom this is their life's work; we've made incredible amounts of progress over the last century. It's just... we're peeking at molecular machinery that is so very small, and moves so quickly that it's nigh impossible to observe in realtime.
