True about RNA Polymerase is:

RNA Polymerase does not require primers (option a) RNA Polymerase has no proof reading activity DNA polymerase has proof reading activity It is DNA dependent RNA Polymerase (option b is wrong) Shine dalgarno sequence is recognized by protein synthesizing machinery i.e. Ribosome (option d), and not RNA Polymerase. RNA polymerase recognize TATA box. Prokaryotes have a single RNA Polymerase. But there are many types in Eukaryotes.
