The exon part of $m-RNA$ contains the code for:

Degeneracy of genetic code refers to$-$

Match the following columns:

Column-$I$ (Genetic Code)	Column-$II$ (Amino Acid)
$P$. $UAA$	$I$. Proline
$Q$. $CCA$	$II$. Glycine
$R$. $GGC$	$III$. Termination
$S$. $AGU$	$IV$. Serine

How many codons are possible in a cell?

$(i)$ The codon is read in mRNA in a contiguous fashion. There are no punctuations.
(ii) Some amino acids are coded by more than one codon.
(iii) $UUU$ would code for phenylalanine.
(iv) $GAA$ is a stop terminator codon.
Comparing the above statements (i-iv),select the correct option marked with $T$ (True) and $F$ (False) with respect to the salient features of the genetic code.

Which one of the following groups of codons is referred to as degenerate codons?
