What is the correct order of elements that comprise a functional protein encoding gene in a prokaryote?
A) Promoter, regulatory region, transcribed region, terminator
B) Regulatory region, promoter, transcribed region, terminator
C) Regulatory region, promoter, terminator, transcribed region
D) Promoter, transcribed region, regulatory region, terminator

Question

Quizplus · Accepted Answer

In a prokaryotic gene, the regulatory region comes first, followed by the promoter, the transcribed region, and finally the terminator. The regulatory region contains the binding sites for specific regulatory molecules that control the expression of the gene. The promoter is the site where RNA polymerase binds to initiate transcription. The transcribed region contains the DNA sequence that is transcribed into mRNA. The terminator signals the end of transcription. Choice B is the correct order of these elements.
