how does termination of translation take place? a stop codon is reached. the 5' cap is reached. the poly-a tail is reached. the end of the mrna molecule is reached.



Answer :

Termination happens when a stop codon in the mRNA (UAA, UAG, or UGA) enters the A site. Stop codons are recognized by proteins called release factors, which fit neatly into the P site (though they aren't tRNAs). Thus Correct Option (a)

Termination is the process through which translation comes to an end. Termination occurs when an mRNA stop codon (UAA, UAG, or UGA) enters the A site. Stop codons are detected by release factors, which are proteins that fit nicely into the P site (albeit they are not tRNAs).

Finally, the ribosome terminates when it hits a stop codon (UAA, UAG, and UGA). Since there are no tRNA molecules that can recognize these codons, the ribosome recognizes that translation is complete. The new protein is then released, and the translation complex comes apart.
