Detailed explanation-1: -According to me if the position of promoter and terminator are exchanged then the template strand would become coding strand so the sequence of mRNA transcribed would be same as the 1st strand (just U in place of T) .
Detailed explanation-2: -The promoter is located towards 5-end of the structural gene. It is a DNA sequence that provides binding site for RNA polymerase. On the contrary, the terminator is located towards 3-end of the coding strand and it usually defines the end of the process of transcription. Was this answer helpful?
Detailed explanation-3: -Final answer: b. 5’ (upstream) end and 3’ (downstream) end, respectively of the transcription unit.
Detailed explanation-4: -Promoters and terminators are stretches of DNA upstream and downstream (respectively) of genes that control both the rate at which the gene is transcribed and the rate at which mRNA is degraded. As a result, both of these elements control net protein expression from a synthetic construct.
