What is the biological meaning of degeneracy (redundancy) in the genetic code?
Answer and explanation
Correct answer: B. Multiple distinct codons can specify the same single amino acid
The genetic code is degenerate because 61 sense codons code for only 20 standard amino acids, meaning multiple codons specify the same amino acid (e.g., leucine has 6 codons). The code is unambiguous (each codon specifies only one amino acid) and non-overlapping.
