A) entire codon
B) third member of a codon
C) first member of a codon
D) second member of a codon
Correct Answer: B
Solution :
It has seen variously that one t-RNA molecule codes more than one amino acid molecules. This is possible due to improper pairing of third codon with the first anticodon of t-RNA. This is called degeneracy of genetic code. This pairing is not very stable and is allowed due to wobbling in base pairing at third position. Wobble hypothesis was proposed by Crick (1965) to explain this phenomenon.
