1.	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.(a) True(b) FalseI have been asked this question during an interview for a job.My enquiry is from Transcription in Eukaryotes : RNA Polymerases in portion Gene Expression : Transcription Prokaryotes of Cytogenetics
Answer» Right option is (b) False Explanation: 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.
