Draw a labelled schematic structure of a transcription unit. Explain the function of each component of the unit in the process of transcription unit.

Explanation

### Step-by-Step Solution

**Step 1: Draw the Schematic Structure of a Transcription Unit**

1. **Promoter Region**: This is the starting point of the transcription unit. It is a specific sequence of DNA that signals the RNA polymerase where to bind and begin transcription.

2. **RNA Coding Sequence**: This is the region of the DNA that is transcribed into RNA. It contains the information that will be translated into a protein.
