DNA vs. RNA – 5 Key Differences and Comparison

WebDefinition. A promoter is a region of DNA where transcription of a gene is initiated. Promoters are a vital component of expression vectors because they control the binding of RNA polymerase to DNA. RNA polymerase transcribes DNA to mRNA which is ultimately translated into a functional protein. Thus the promoter region controls when and where ... WebRNA polymerase I.
