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 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 point mutation.
b. A translocation.
c. A nonsense mutation.
d. A duplication.
e. An inversion.

The correct option is e

Explanation:

An inversion mutation is a situation in which a sequence of the gene on a chromosome breaks out and rearranges itself from reverse (to the beginning) and then attaches itself back to the point of breakage of the same chromosome.

From the question, mutation changed the gene sequence from ABC*DEFGH to ABC*DGFEH. From this mutation, it can be seen that the gene sequence "EFG" broke-out, rearranged itself from reverse to the beginning as "GFE" and then attached itself back to the points of breakage.

NOTE: This type of inversion is called paracentric inversion since the centromere (represented as * in the question) is not part of the breakage.

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.
