Four different transcription units are shown below. Choose the option with the correct image.
Show Hint
To solve any transcription unit orientation problem instantly, remember this single rule: All structural positions (Promoter and Terminator) are defined entirely with respect to the coding strand. Promoter is always at the $5'$-end of the coding strand; Terminator is always at the $3'$-end of the coding strand.
