Genetic Code and Regulation - Medical Science

Q1:

The genetic code is degenerated. Which of the following codons represents the principle of degeneracy?

A UAA and UAC

B AUG and AUA

C CAU and CAC

D UUA and UUC

ANS:C - CAU and CAC

Degeneracy means the first two Nucleotides which are present t-RNA anti-codon that's strictly follow the base pairing rules but third Nucleotide is not follow the base pairing rules. Then changes occurs in only one Amino acid of the protein.
