Mention two functions of the codon AUG.

Explanation

### Step-by-Step Solution:

1. **Identify the Codon**: The codon in question is AUG. Codons are sequences of three nucleotides in mRNA that correspond to specific amino acids or signals during protein synthesis.

2. **Function 1 - Coding for Methionine**: The first function of the codon AUG is that it codes for the amino acid methionine. Methionine is the first amino acid that is incorporated into a nascent polypeptide chain during the process of translation.

3. **Function 2 - Start Codon**: The second function of the codon AUG is that it serves as a start codon. This means that it signals the beginning of the translation process, indicating where the ribosome should start synthesizing the protein from the mRNA template.
