From the following, identify the correct combination of salient features of Genetic code.
Options
- AUniversal, Non-ambiguous, Overlapping
- BDegenerate, Overlapping, Commaless
- CUniversal, Ambiguous, Degenerate
- DDegenerate, Non-overlapping, Non-ambiguous
Correct answer
D. Degenerate, Non-overlapping, Non-ambiguous
Step-by-step solution
The correct combination of salient features of Genetic code is degenerate, Non-overlapping, Non-ambiguous. These are explained as one codon codes for only one amino acid, hence genetic code is unambiguous and specific. Some amino acids are coded by more than one codon, hence the code is degenerate. The codon is read in mRNA in a contiguous fashion. There are no punctuations and overlapping.
