The three RNA codons UAA, UGA, and UAG serve as stop codons in the process of translation during protein synthesis.

Explanation:

  • Stop codons are responsible for signaling the termination of protein synthesis. When the ribosome encounters any of these codons on the mRNA strand, it recognizes that the protein chain is complete and releases the newly synthesized polypeptide.
  • UAA, UGA, and UAG do not code for any amino acids, which is why they are effective in halting the translation process.

In summary, the function of the RNA codons UAA, UGA, and UAG is to act as stop codons, terminating the translation process in protein synthesis.
