A) The genetic code is different for different domains of organisms.
B) The genetic code is universal the same for all organisms).
C) More than one codon can specify the addition of the same amino acid.
D) A single codon can specify the addition of more than one amino acid.

Quizplus · Accepted Answer

Redundancy in the genetic code means that more than one codon (a sequence of three nucleotides) can specify the addition of the same amino acid. This reduces the impact of mutations or errors in the DNA sequence, as a change in a single nucleotide may not result in a different amino acid being incorporated into the protein. However, not all codons are redundant and the genetic code is universal (the same for all organisms).
