Transcription of mRNA Complementary to DNA

Once the RNA polymerase/sigma factor complex recognizes the correct promoter, the sigma factor dissociate from the RNA polymerase and the enzyme begins to unwind the helix of the DNA creating a region of nonpaired deoxyribonucleotides that serve as a template for RNA synthesis. Transcription is under control of the enzyme RNA polymerase which is not shown here.
