Cells typically respond to DNA damage in three ways: by ceasing to grow and divide until the damage is repaired, by permanently ceasing to grow
and divide, or by dying in 2010 a group of scientists reported that a
certain kind of immune reaction can cause DNA damage that leads to a
fourth response. DNA damage can turn off genes involved in cel-signaling
pathways. Turning off these genes can cause less-mature cells to divide
too rapidly, often leading to the development of —-
A. tumors
B. allergies
C. hemophilia
D. cardiovascular disease
