Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
A set of triplets that codes for an amino acid is called codon. Ochre (UAA), opal (UGA) and amber (UAG) are stop codons that causes termination of protein synthesis. Assertion is correct. Since, these codons do not code for any amino acid, they cause termination of translation when encountered in mRNA during protein synthesis irrespective of completion of the process.
So, the correct option is B.
