Vedclass · Answer

(B) In bacteria,there are two types of $tRNA$ for methionine: $tRNA_f^{Met}$ (initiator $tRNA$) and $tRNA_m^{Met}$ (elongator $tRNA$).$tRNA_f^{Met}$ is used for the initiation of protein synthesis,while $tRNA_m^{Met}$ is used for the incorporation of methionine at internal positions of the polypeptide chain.Therefore,the Assertion is correct.$AUG$ codes for methionine,and the genetic code is unambiguous,meaning one codon codes for only one amino acid.However,the reason provided does not explain why two different $tRNA$ molecules are required for the same amino acid in bacteria.Thus,both statements are correct,but the Reason is not the correct explanation of the Assertion.

$A$: In bacterial translation mechanism,two $tRNA$ are required for methionine.
$R$: $AUG$ codes for methionine and it shows nonambiguity.
