Question

Mark the statement which is INCORRECT about the transcription unit?

(a) It is a transcribed segment of DNA

(b) Eukaryotes have monocistronic transcription unit

(c) Prokaryotes also have a monocistronic transcription unit

(d) Immediate product of transcription is primary transcript

I have been asked this question in a national level competition.

I'd like to ask this question from Transcription in chapter Molecular Genetics of Life Sciences

Answer 1

Right choice is (c) Prokaryotes also have a monocistronic transcription unit

To explain: Transcription unit is the transcribed segment of DNA. If the transcription unit carries information of one gene, it is called monocistronic while a set of adjacent genes when transcribed as a unit called polycistronic.
