Mention two functions of the codon AUG.

Explanation

### Step-by-Step Solution:

1. **Identify the Codon**: The codon in question is AUG.

2. **Function as a Start Codon**: The first function of the codon AUG is that it serves as a start codon. This means that it signals the beginning of the translation process in protein synthesis. It is the first codon that is recognized by the ribosome during translation.

3. **Amino Acid Coding**: The second function of the codon AUG is that it codes for the amino acid methionine in eukaryotes. In prokaryotes, it codes for a modified form of methionine known as formylmethionine (FMET). This distinction is important in understanding the differences between eukaryotic and prokaryotic protein synthesis.
