Answer: d. All codons only after the point at which the mutation occurred.
Explanation:
Mutation can be defined as the change that occurs at the genetic level.
A frameshift mutation can be defined as the genetic mutation in which the deletion or insertion of the number of the nucleotide in the sequence of DNA results.
The frameshift mutation changes the reading frame of the group of codon from the point where the change has occurred.
This results in the completely different translation from the previous sequence.
