A mutation occurs in a brain cell. This mutation will be passed on to
A.
other body cells.
B.
cells produced when the mutant cell divides.
C.
neighboring brain cells.
D.
offspring.

The correct answer is B. Cells produced when the mutant cell divides. What is being described here is basically how cancer is spread. A single cell is enough to get the mutation and become corrupt in order to create many many new cancer cells that will eventually kill the person if not treated. Some are easily treatable, some incurable.
