The fact that several distinct codons can encode the same amino acid (e.g., serine, arginine) is termed:
- A
Nonsense
- Bcheck_circle
Degeneracy (redundancy) of the genetic code
- C
Wobble at the anticodon's first position
- D
Universal mutation
Explanation
The genetic code is degenerate: most amino acids are specified by more than one codon, which buffers many third-position mutations against amino acid changes.
