The termination of protein synthesis occurs upon recognition of what codon?

Explanation:
Termination of protein synthesis happens when the ribosome reads a stop codon in the mRNA. Stop codons—UAA, UAG, and UGA—do not code for any amino acid. Instead, release factors recognize them and promote release of the newly made polypeptide and disassembly of the ribosome. The start codon marks the beginning of translation, a codon is any three-nucleotide unit, and an anticodon is the tRNA’s triplet that pairs with a codon during elongation. So recognizing a stop codon is the signal to end translation.
