Question

what type of mutation is it when a stop codon is changed into a meaningful codon

Solution

Dear student,

Basically there are non-stop mutations, which differ from non-sense mutations, because they do not create a stop codon but delete a stop codon. Thus, it is a point mutation that occurs within the stop codon and thus it leads to continued translation of an mRNA.
