7. According to Nature. com, "A genetic mutation known as CCR5-delta 32 is responsible for the two types of HIV resistance that exist. CCR5-delta 32 hampers HIV's ability to infiltrate immune cells. The mutation causes the CCR5 co-receptor on the outside of cells to develop smaller than usual and no longer sit outside of the cell." Which statement explains how these mutations occur?

a. A mutation occurs when HIV enters the cell

b. A mutation occurs when nucleic acids are replicated

c. A mutation occurs during mitosis

b. 50%

c. 19%

d. 100%
