RNA polymerse which is on the promoter, moves to the structural genes to transcribe them. However, it happens when:

RNA polymerase which is on the promoter, moves to the structural genes to transcribe them. However, it happens when

In the lac operon, the structural genes are switched off when

In the lac operon, the structural genes are switched off when

In the lac operon, the structural genes are switched off when

In an operon what is present in between the promoters and structural genes.

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 .

Which of the following is true about the promoter gene?
