DNA replication occurs by the sequential unzipping of segments of the double helix. Each new nucleotide is brought into position by DNA polymerase and is added to the growing strand by the formation of a phosphate ester bond. Thus, two double helixes form from one, and …
WebInitiation of transcription begins with the binding of RNA polymerase to the promoter. Transcription requires the DNA double helix to partially unwind such that one strand can be used as the template for RNA synthesis. The region of unwinding is called a transcription bubble. Figure 3.
