Cotranscriptional translation: A ribosome follows an RNAP on the mRNA transcript the RNAP generates. Do the two molecular machines “dock” together to form a supercomplex, the expressome, when the ribosome catches up? If yes, is their coupling direct or mediated by Nus factors? Is the coupling tight or transient and stochastic? To see this figure in color, go online.
