Select the correct statements regarding the process of transcription in eukaryotes. (i) The strand of dsDNA which takes part in transcription process is called as coding strand. (ii) The enzyme RNA polymerase can catalyse polymerisation only in one direction i.e. , 5' rarr 3' .

Mark the incorrect differences between eukaryotic and prokaryotic transcription. I. In eukaryotes , the genes are split having exons and introns while in prokaryotes it isn't . ii The structural gene which is to be transcribed is generally mono- cistronic in prokaryotes and poly-cistronic in eukaryotes . III . The RAN formed with the help of RNA polymerase in eukaryotes requires future processing to function as m-RNA while in prokaryotes it is directly used as m - RNA. IV. In eukaryotes, RNA polymerase binds to the promoter region while in prokaryotes it binds to the operator region .
