Methionine is specified by the codon AUG, which is also known as the start codon. Consequently, methionine is the first amino acid to dock in the ribosome during the synthesis of proteins.

The start codon is typically AUG, which stands for methionine, and signals the beginning of that particular protein synthesis ...

How does DNA determine an organism’s characteristics? A process called translation decodes RNA created during transcription, and uses it to create proteins that perform specific cellular functions.
