Question
**Examine the following mRNA transcripts:**

**Wild type:** 5’ CACUGAUGCACGGCAUCAU 3’  
**Mutant:** 5’ CACUGAUGCACGGCAUGAU 3’

**What kind of mutation is occurring in the mutant sequence compared to the wild type sequence?**

**Genetic Code Chart:**

The chart is a codon table used to identify which amino acid corresponds to each mRNA codon. It is organized by the first, second, and third bases of the codon:

- **First Base (Y-Axis):** U, C, A, G
- **Second Base (X-Axis):** U, C, A, G
- **Third Base (Z-Axis on the right side):** U, C, A, G

For example, the codon AUG corresponds to Methionine (Met) and also acts as the start codon.

**Options for Type of Mutation:**

- Silent
- Missense
- Nonsense
- Frameshift

Use the chart to determine the amino acid sequence for both the wild type and mutant mRNA transcripts and identify the type of mutation that has occurred.
