**Gene Transcription and mRNA Processing**

In this activity, we will identify the parts of a gene or transcription unit and pinpoint the sections that are transcribed into mRNA.

### Gene X - Coding Strand Sequence:
The sequence of gene X is visually mapped with colors indicating specific regions:

- **AGTATATG** (Green)
- **CTCTGCAA** (Purple)
- **TGCTC** (Blue)
- **AATAGCGGATC** (Orange)

### Resulting mRNA Sequence:
From the transcription of gene X, the mRNA sequence is:
- **CUCUGCAAAAUAGCGAUC**

### Key Components:
Based on the color-coded regions, identify the parts of the gene:

- **Purple**: Corresponds to an intron.
- **Green**: Corresponds to an exon.
- **Blue**: Represented as a promoter.
- **Orange**: Represents a terminator.

These components play crucial roles in the regulation and expression of genes, with exons coding for protein sequences and introns often being non-coding, regulatory sequences. Promoters and terminators are involved in the initiation and termination of transcription, respectively.
