I can't post pictures at all, what the fuck is going on this time?

This fucked me up.
How does it just fly through empty space like that and slam into the correct slot?
Is this similar to how magnets cannot land on like poles?!

Electrical charges distribution and steric effects.
Also note that it's only one of a whole bunch of identical molecules that binds the target in the end.

For example see vid related.
Usually there are only 2 copies of a gene but you will find thousands of regulator proteins for it inside the cell.
When a gene need to be switched on you have:
- extracellular or intracellular signal triggers the production of second messengers
- each second messenger triggers the production of a third messenger
- repeat for variable n times (depending on the specific signal way)
- In the end you have whole bunch of regulators proteins
This process is called signal amplification.

Chances are that eventually one will collide with the right spot of dna trough brownian motion and trigger the binding and then the reaction

Probability of collision due to concentration of enzyme and substrate

That's a fucking lie.

These videos are fucking CGI lies.

They aren't even simulations. Hell we can't even simulate to these timescales.

It fucking doesn't fly on their. Random fucking chance causes the enzyme to bounce around there eventually.

Not a gif or a webm but still useful

it's not in empty space, is in water

>Hell we can't even simulate to these timescales
Simply not true worded in that way.

Is this supposed to be a jew? Why is it so stereospecific?
