Among the following choose the codons that specify the same amino acidA. CGA                        B. GGA                          C. AGA                                   D. UGA

The codons CGA and AGA specify the same amino acid Arginine which is an example for degeneracy of genetic code. GGA indicates the amino acid Glycine. Codon UGA does not indicate any amino acid and it is a non-sense or chain terminating codon.
