The mutant DNA is shown below What is the final effect of this base change on the resulting polypeptide? ?:UUGencodes Leucin). Mutant DNA sequence 3..AACACCCAGGAGCC.. semplate strand s T TG T G G G T C CT C G G neneemplate strand Protein sequenceLeu OA The mutant polypeptide has the same length wigh a totally different sequence of amino acids as of the normal one O& The mutant polypeptide has the same length as of the normal polypepside but dffers in just OC This is a nonsense mutation, and the mutant polypepäide is shorter than the normal one ?D.This-asense mutation, and the mutant polypeptide is longer than the nonnal one. K.Explanation / Answer
The change in one base lead to no change in the amino acid of the parent protein. . Hence, option B is correct.
