Solution

The correct option is C Assertion is incorrect but Reason is correct
Eukaryotic mRNA is called monocistronic i.e., formed from one gene. These have been described to contain only one initiation site, who gave one mRNA-one polypeptide chain hypothesis. The terminator codon is present on mRNA molecule, which stops the formation of a polypeptide chain at that point, the three termination codons are UGA, UAA and UAG. So, the correct answer is 'Assertion is incorrect but Reason is correct'.
