Question

If more than one code designates the single amino acid it is

• A. Degenaracy of codon
• B. Overlapping of codon
• C. Nonsense codons
• D. None of the above

Answer 1

The correct option is A Degenaracy of codon

In genetic code, three nucleotide bases code for one amino acid. With four bases, there are 64 possible combinations of three letter genetic code. Of these 64 genetic codes 61 represents 20 amino acids and three for stop signals. Thus there are more than one codon for more than one amino acid. This is called degeneracy of genetic code. The term "degenerate" simply refers to the fact that the translation from nucleotide codons to amino acids isn't one to one. Some parts of the genetic code are redundant.
