Spacer that does not unde
Spacer that does not undergo this process includes Bam islands. The inchworm model of this process refers to the discontinuous movement of one enzyme. This process in bacteria terminates with the addition of a rho factor, and initiates using a sigma factor. Factors named for this process have DNA-binding domains, such as zinc finger motifs. Regions known as promoters indicate where this process begins. Modifications after this process include the addition of a five-prime cap. For 10 points, name this process that encodes messenger RNA and precedes translation.
