The total genetic message would be only slightly changed.
A commaless code would not have the comma bases and can be
represented thus:
UUU CUC GUA UCC ACC..........Bases
Phe Leu Val Ser Thr........... Amino acids
In such a code any mutation involving a deletion of a base (-C) would result in a drastic change in the genetic message.
UUU UCG UAU CCA CC..........Bases
Phe Ser Tyr Pro..........Amino acids
The entire series of amino acids following the deletion would change.
All the available evidence indicates that the code is commaless, i.e. there are no demarcating signals between codons.
The work of Khorana and his associates cited below gives clear evidence of a commaless code
