Which of the following substances act as a key growth regulator

Which of the following statements are correct regarding transcription ?
(i) rRNAs plays structural and catalytic role during translation.
(ii) There is single DNA-dependent RNA polymerase that catalyses transcription of all types of RNA in bacteria.
(iii) RNA polymerases are able to catalyse all the three steps of transcription i.e., initiation, elongation and termination.
(iv) The RNA polymerase is only capable of catalysing the process of elongation.
(v) Many times the translation can begin much before the mRNA is fully transcribed in bacteria, so transcription and translation can be coupled in bacteria.
(vi) In eukaryotes, there are at least three types of RNA polymerases in the nucleus.
(vii) In eukaryotes, the primary transcripts called hnRNA contain both the exons and the introns and are non-functional.
