Answer:

Point mutation is the correct answer.

Explanation:

Sickle cell disorder is a genetic disorder that is caused because of point mutation.

Due to point mutation protein lose their function which results in sickle cell disease.

The mutation in the Hemoglobin Subunit Beta gene in Sickle cell diseases affects the hemoglobin and the red blood cells molecules that transfer oxygen to the cells.

Sickle cell diseases can lead to stroke, organ damage,blindness, priapism,hypertension, acute chest problems.

The question is incorrect as it does not have the options which are:

A) point

B) frameshift

C) nonsense

D) nondisjunction

E) both B and D

Answer:

Point mutation

Explanation:

Sickle cell disease refers to the disease which is caused by the change in the shape of the oxygen delivering cell in the blood called the red blood cells.

The shape of the red blood cells becomes crescent of sickle due to the distortion in the shape of the hemoglobin molecule which binds oxygen.  The distortion in the shape of the hemoglobin molecule is genetically controlled and occurs when the person possesses both the copies of the allele which changes the shape.

The mutated gene changes the shape of the hemoglobin by changing the glutamic acid amino acid by valine at the 6th position. Since the mutation changes the amino acid at only one position that is only 6th position therefore it is considered a point mutation.

Thus, a point mutation is correct.
