**Transcription and Translation of a DNA Sequence:**

A sequence of a DNA template strand is shown below:

```
3’ TAA ACG GAC CGA TTT GCA 5’
```

**Codon Table:**

The table provides the correlation between mRNA codons and their corresponding amino acids. It is organized by the first, second, and third bases of the codons:

| First Base in the Codon | Second Base of the Codon | Third Base in the Codon |
|-------------------------|--------------------------|-------------------------|
| U                       | C                        | A                       |
| Phenylalanine, Serine, Tyrosine, STOP, Cysteine    | U, C, A, G     | U, C, A, G |
| Leucine, Proline, Histidine, Arginine              | U, C, A, G     | U, C, A, G |
| Isoleucine, Threonine, Asparagine, Serine          | U, C, A, G     | U, C, A, G |
| Valine, Alanine, Aspartic Acid, Glycine           | U, C, A, G     | U, C, A, G |

**Multiple Choice Options:**

- Serine - Leucine - Proline - Asparagine - Lysine - Arginine

- Tryptophan - Phenylalanine - Leucine - Glycine - Asparagine - Serine

- Arginine - Leucine - Proline - Asparagine - Lysine - Arginine

- Isoleucine - Cysteine - Leucine - Alanine - Lysine - Arginine

Use this information to understand DNA transcription and to determine the correct sequence of amino acids encoded by the given DNA template strand.
