Nonsense mutation always produces a stop codon
The genetic code is called non-overlapping because adjacent codons can not overlap, whereas in this case, the code is overlapping.
<h3>What does 'overlapping code' mean?</h3>
The genetic code does not overlap because the same nucleotide in the sequence cannot be used to encode two different codons.
In genetics, overlapping refers to a feature of the genetic code associated with how this nucleotide code is read.
In conclusion, the genetic code in this case is overlapping.
