What is the significance of the degeneracy of the genetic code?
What is the significance of the degeneracy of the genetic code?
- It allows one amino acid to be encoded by multiple codons. (correct)
- It ensures that each codon encodes a unique amino acid.
- It prevents the synthesis of polypeptide chains.
- It results in a one-to-one correspondence between codons and amino acids.
