Vedclass · Answer

(A) The genetic code consists of $64$ codons in total. Out of these $64$ codons,$61$ 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 $64$ codons do not code for amino acids; only $61$ do. Statement $(i)$ is correct as codons are triplets of nucleotides. Statement $(iii)$ is correct as the genetic code is unambiguous,meaning one codon codes for only one specific amino acid. Statement $(iv)$ is correct as the genetic code is nearly universal (from bacteria to humans). Statement $(v)$ is correct as $	ext{AUG}$ acts as an initiator codon (coding for methionine) and also codes for methionine in the middle of a polypeptide chain.
