* Universality: The genetic code is largely the same across all living organisms, from bacteria to humans. This means the same codons (three-nucleotide sequences) generally code for the same amino acids.
* Redundancy: Multiple codons can code for the same amino acid. This provides some protection against mutations.
* Unambiguous: A single codon never codes for more than one amino acid.
* Non-overlapping: Codons are read sequentially, without any overlap.
Now, let's consider the options you're given. To answer your question, I need the list of characteristics you're considering. Please provide the list so I can identify the one that is *not* a characteristic of the genetic code.
