In this article we will discuss about the role of RNA polymerase in transcription. RNA polymerase enzymes are complex enzyme which in E. coli is made up of 5 subunits or polypeptide chains designated β, β', α, σ and ω with respective molecular weights of 160,000, 150,000, 90,000, 40,000 and 10,000. The α chain is present twice, others only once. [...]
