Which statement explains how a DNA mutation causes sickle-cell anemia?(1 point)

DNA mutation causes a change in the amino acid sequence for hemoglobin, which causes a change in the shape

Explanation:

Sickle cell mutation is a mutation that affect the production of red blood cell that is needed for the transport of oxygen in the bloods stream.

sickle cell mutation is a result of change in the amino acid which are building blocks of the protein hemoglobin.

The protein is what gives red cells their color, it has two subunits. The alpha

and beta subunit. There is a change in the arrangements of amino acid sequence and that is the basis for the sickle cell shape, beta subunit has valine an amino acid at position 6 instead of the glutamic acid. This alteration results in sickle cell problems that occur in people.
