Consider the transcription unit given in the following diagram and choose the correct statements:
I: | The promoter on the template is situated upstream and 5’ to the structural gene. |
II: | It is the presence of the structural gene that defines the template strand. |
III: | The coding strand does not code for anything and is displaced during transcription. |
1. | I and II only | 2. | I and III only |
3. | II and III only | 4. | I, II and III |
