The normal sequence of genes along a hypothetical chromosome is ABC*DEFGH,where letters represent genes and the asterisk (*)represents the centromere.A mutation event results in a chromosome in which the sequence of genes is ABC*DGFEH.This type of mutation is
A)a nonsense mutation.
B)an inversion.
C)a translocation.
D)a duplication.
E)a point mutation.
