I'm having trouble wrapping my head around this one. I know that ribosomes are responsible for protein transcription but I don't get how they do it.

Can someone either explain in simple terms how exactly they do it (not something like "they just do") and I do mean HOW they do it, or point me in the direction of a page that does?

As the earth rotates 15 degrees in one hour west to east, suppose a plane remains stationary in space & then after one hour the point of earth coming below it will be the place which was 15 degrees to the west than when it started in stationary position ?
Is this possible (if we think that a plane can remain stationary)?
