The RNA sequence below depicts the part of a $330$ nucleotides long $\text{mRNA}$ and it encodes the $\text{C}$-terminal portion of a protein.
$5^{\prime}-\ldots \ldots$ $\text{AAC ACC ACG ACC CAU GUG GCG AGA CGG UAG}$ - $3^{\prime}$
A mutation was identified in this $\text{RNA}$ denoted as $322 \mathrm{~A} \rightarrow \mathrm{U}$. This nucleotide change is represented by which of the following class(es) of mutation?
- Missense mutation
- Non-sense mutation
- Transversion mutation
- Silent mutation
