About the movement of organelles: There are molecular motor proteins that haul them around!
Let’s consider the eye, which is but one of many subsystems (along with the brain, heart, liver, lungs, etc.) in higher animals that coordinate their tasks to keep an organism alive.
In “real time” they show the function of an enhancer in switching a gene from off to on.
The nucleus is a beehive of activity, where information is not just stored but processed, protected, transcribed, and duplicated by highly complex machines.
Details of the nuclear pore complex, one of the largest and most complex protein systems in the cell, come into sharper focus as a team watches how it validates a messenger RNA.
