Tailgating ribosomes cause rear-end collisions

During prokaryotic transcrption and translation, the ribosome and RNA polymerase play bumper cars. With the RNA polymerase as the lead car, ribosomal tailgating leads to crashing and increases transcription speed – at the expense of accuracy. But, hey, when you’re in a hurry, who’s got time for being precise? Just don’t pause for too long, or you might cause a cellular pile-up.
