Vedclass · Answer

(C) The Wobble hypothesis,proposed by Francis Crick,states that the third base of a codon (the $3'$ end) can pair with more than one base in the anticodon of a $tRNA$ molecule.This flexibility allows a single $tRNA$ to recognize multiple codons that code for the same amino acid,thereby reducing the total number of $tRNAs$ required for protein synthesis.Code degeneracy refers to the fact that multiple codons can specify the same amino acid.Wobbling is a mechanism that facilitates the reading of these degenerate codons by fewer $tRNAs$,but it is not the cause of degeneracy itself; rather,it is a consequence of the genetic code's structure.Therefore,the Assertion is correct,but the Reason is incorrect because wobbling does not increase the effect of degeneracy; it simply accommodates it.

Column-$I$	Column-$II$
$A. \; AUG$	$1. \; \text{Phenylalanine}$
$B. \; UAA$	$2. \; \text{Methionine}$
$C. \; UUU$	$3. \; \text{Tryptophan}$
$D. \; UGG$	$4. \; \text{Termination}$

$A$: Wobbling reduces the number of $tRNAs$ required for polypeptide synthesis.
$R$: It increases the effect of code degeneracy.
