Here's why:
* Translation: The process of building a protein from an mRNA template is called translation. This process involves reading the mRNA codons (three-nucleotide sequences) and matching them to specific amino acids.
* Stop Codons: Stop codons act as signals to the ribosome (the protein-building machinery) to stop adding amino acids to the growing polypeptide chain. They don't code for any amino acid, their sole function is to terminate translation.
