Vedclass · Answer

(A) The genetic code consists of $64$ codons. Out of these,$61$ codons code for amino acids,while $3$ codons $(UAA, UAG, UGA)$ act as stop codons (termination codons) and do not code for any amino acid. Therefore,statement $ii$ is incorrect because not all $64$ codons code for amino acids. Statements $i, iii, iv,$ and $v$ are correct: the code is a triplet,it is unambiguous (one codon codes for only one amino acid),it is universal (the same codon codes for the same amino acid in all organisms),and $AUG$ has dual functions (it codes for methionine and acts as an initiator codon).

Column-$I$	Column-$II$
$(a)$ $UUU$	$(1)$ Serine
$(b)$ $GGG$	$(2)$ Methionine
$(c)$ $UCU$	$(3)$ Phenylalanine
$(d)$ $CCC$	$(4)$ Glycine
$(e)$ $AUG$	$(5)$ Proline
