RNA-Polymerase
In Autumn, the proteins in our cells, change colors and put on a fantastic display before they flutter softly to the ground… no wait, that’s leaves. Nonetheless, this RNA polymerase sports the latest fall colors, inspired by the view from my windows. RNA Polymerases create strands of RNA from a DNA template in the nucleus. The RNA can go on to be used in the process of protein translation outside the nucleus. Sadly, cellular proteins are too small to actually have any color at all; the wavelengths of visible light are much larger, but at least we don’t have to rake them.

And here it is in animated GIF form:
