Ultraviolet radiation increases the likelihood of a cell becoming malignant primarily because UV radiation
a. breaks DNA into fragments.
b. causes DNA damage that leads to mutations.
c. makes RNA polymerase more error-prone.
d. induces melanocytes to express more melanin.

The signature mutation caused by ultraviolet light is a CC to TT mutation, caused when a CC dimer is mispaired with two adenine bases during replication. Because of these mutations, the connection between ultraviolet damage to DNA and cancer is quite clear.
