From lots of experiments, from lots of different scientists, we know a lot about what these molecules look like, how they move around in the cell, and that this is all taking place in an incredibly dynamic environment.
Iz puno eksperimenata, od puno različitih znanstvenika, znamo puno o tome  kako te molekule izgledaju, kako se kreću u stanici, i da se sve ovo događa u izuzetno dinamičnom okruženju.
