Question

What are the three stop codons that signal the termination of translation?

विकल्प

• UAA, UAG, and UGA

• AUG, UAA, and UGA

• UUA, UAG, and UCA

• UAA, UAC, and UGA

Answer 1

The three stop codons are UAA, UAG, and UGA. These codons do not code for any amino acid and do not have corresponding tRNAs. Instead, when the ribosome encounters a stop codon, release factors bind and catalyze the release of the completed polypeptide chain from the tRNA, ending translation.
