A substitution mutation is one in which one nucleotide base is changed to another
2. A substitution mutation is one in which one nucleotide base is changed to another Suggest ONE substitution A G mutation in the DNA that would cause the first amino acid in the "# of Eyes" gene to change from alanine (Ala) to valine (Val). In the table below, write the original.3. There is a substitution mutation in the gene for Fangs in which the first DNA base changes from guanine to thymine. The mutation results in a genetic disorder...
