Question

Early in genetic research, it was suggested that the genetic code might be made up of overlapping codons in which the last two bases of one codon make up the first two bases of the next codon, as below:
mRNA codons
overlapping code GGUAUA 1st codon = GGU
2nd codon = GUA

nonoverlapping code GGUAUA 1st codon = GGU
2nd codon = AUA

Supposing it were discovered that, in a life-form from another planet, even a single base pair substitution in the DNA caused three adjacent amino acid changes in the protein coded for. Would you conclude that the code was overlapping or nonoverlapping? Explain your logic.

Answer 1

The genetic code is called non-overlapping because adjacent codons can not overlap, whereas in this case, the code is overlapping.

What does 'overlapping code' mean?

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.
