This is electron microscopy image of a polyribosome. Imagine that this image is taken from a prokaryotic cell: Which end (A or B) has longer proteins coming from it (remember that they are folding as they are being made). _____ What does this tell you about which end is the 5′ end of the mRNA? Finally, the other end has been cut from this picture, but what would you expect to see (in terms of the mRNA molecule’s 3′ end)? Finally, how would this be different in a eukaryote
