A start codon is a specific sequence of nucleotides in mRNA that signals the beginning of translation, the process by which proteins are synthesized. The most common start codon is AUG, which codes for the amino acid methionine. When the ribosome encounters a start codon during translation initiation, it assembles around the mRNA and begins synthesizing the corresponding polypeptide chain. This process is crucial for ensuring that proteins are produced correctly and efficiently in cells.
