5’ (upstream) end and 3’ (downstream) end, respectively of the transcription unit
|
|
|
the 5’ (upstream) end
|
|
|
the 3’ (downstream) end
|
Detailed explanation-1: -Final answer: b. 5’ (upstream) end and 3’ (downstream) end, respectively of the transcription unit.
Detailed explanation-2: -<br> Terminator is the region of the transcription unit that ends the process of transcription. It is located towards 3.-end (downstream) of the coding strand.
Detailed explanation-3: -For example, most promoters lie immediately upstream of the transcription unit (transcription proceeds in an upstream to downstream direction), and most contain what is known as a TATA box; this is a sequence that is recognized and bound by a so-called TATA binding protein.
Detailed explanation-4: -The promoter is located towards the 3’ end of the structural gene with respect to the template strand. 3. The terminator is located towards the 3’ end of the structural gene with respect to the template strand.
Detailed explanation-5: -A promoter is a region of DNA that generally is located upstream of a gene and facilitates and regulates its transcription.
