WebStep 1: Initiation. Initiation is the beginning of transcription. It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter. This signals the DNA to unwind so the enzyme can ‘‘read’’ the bases in one of the DNA strands. The enzyme is now ready to make a strand of mRNA with a complementary sequence of bases. edge import from chrome androidWebThe in vitro reconstruction of life-like self-reproducing systems is a major challenge in in vitro synthetic biology.
