From the following, identify the correct combination of salient features of Genetic Code.

1. Degenerate, Non-overlapping, Nonambiguous
2. Universal, Non-ambiguous, Overlapping
3. Degenerate, Overlapping, Commaless
4. Universal, Ambiguous, Degenerate

Correct answer: Degenerate, Non-overlapping, Nonambiguous

Solution

The genetic code is degenerate because most amino acids are specified by more than one codon. It is non-overlapping and nonambiguous because each nucleotide is read in only one triplet frame, and each codon specifies only one amino acid.
