All the RNA polymerases share 5 common subunits, which are present in all the three polymerases and are all alike. State whether the statement is true or false. Correct Answer False

Although these 5 subunits are common to all the RNA polymerases yet they share some subtle differences- the CTD of the beta prime subunit of pol II has heptad repeat. Also the alpha subunits in RNA pol II are quite different from that of pol I and III.
