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.
