**Question 9**

Shown is a segment of DNA with its promoter and terminator. Start and end of transcription are marked with an arrow. The length of each part is marked with bases underneath. What is the size of the mRNA when it is first made (immature, before processing)?

- **Diagram Explanation:**

  The DNA segment is illustrated with various sections labeled and color-coded:

  - **Promoter** (blue oval): Marks the beginning of transcription.
  - **Exon 1** (orange rectangle): Length is 27 bases.
  - **Intron 1** (black line): Length is 15 bases.
  - **Exon 2** (green rectangle): Length is 30 bases.
  - **Intron 2** (black line): Length is 17 bases.
  - **Exon 3** (orange rectangle): Length is 27 bases.
  - **Intron 3** (black line): Length is 14 bases.
  - **Exon 4** (green rectangle): Length is 30 bases.
  - **Terminator** (purple oval): Marks the end of transcription.

  - The entire segment starts at the promoter and ends at the terminator, with base lengths indicated for each feature.

**Options for the size of the mRNA:**
- 160 bases
- 175 bases
- 190 bases
- 205 bases

To find the total size of the immature mRNA, add the lengths of all exons and introns: 

27 (Exon 1) + 15 (Intron 1) + 30 (Exon 2) + 17 (Intron 2) + 27 (Exon 3) + 14 (Intron 3) + 30 (Exon 4) + 15 (from the promoter region) + 30 (from the terminator region) = 205 bases.
