Recognize that protein synthesis regulation (i.e., changes in gene expression) allow cells to respond to changes in the environment. WebConnection for AP ® Courses. During transcription, the enzyme RNA polymerase moves along the DNA template, reading nucleotides in a 3′ to 5′ direction, with U pairing with A and C with G, and assembling the mRNA transcript in a 5′ to 3′ direction. In prokaryotes, mRNA synthesis is initiated at a promoter sequence on the DNA template.
