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?

Cells are tiny and the speed of sound is how fast air molecules move. Proteins are also not bouncing around as fast but it’s very still quick relative to their size. Next, often there are multiple copies of each component. That’s half the story, larger cells also have various means to clump things together to improve the odds. https://en.wikipedia.org/wiki/Endoplasmic_reticulum

PS: Speed of sound is 343 m/s, diameter of a cell nucleus is ~ 0.000006m to give an idea.

Speed of sound in water is faster.

Yep, and speed of sound is lower than the average speed of individual molecules. But, I was aiming for an intuitive understanding rather than accuracy involving brownian motion etc.
