tRNA pun

I thought of this one day while brushing my teeth. The images make it easier, but this was the original joke:

So one tRNA diffuses up to another and says, “It is frigid in here!” The other tRNA responds, “Well, then go get your codon.”

Read it out loud to get the joke. It isn’t that funny, sadly, but it made me laugh when I thought of it.

The specific tRNA in the image is yeast Phenylalanine tRNA, which I got from RCSB. The number is 1ehz. I used pyMOL to orient and take the images, and then GIMP to add in speech bubbles.
