The process of removal of introns in a defined order in a transcription unit is called . . . . . . .

During transcription,the holoenzyme $RNA$ polymerase binds to the $DNA$ strand,and the $DNA$ forms a saddle-like structure at that site. What is this sequence called?

Give scientific reasons: Transcription and translation could be coupled in prokaryotic cell but not in eukaryotic cell.

What is the location of the promoter in a transcription unit?

Which of the following is responsible for the transcription of $tRNA$ and $snRNAs$?

In eukaryotes,$RNA$ polymerase $III$ catalyses the synthesis of
