8. Skin cancer is a disease that occurs when skin cells grow in an uncontrolled way. It can be caused by UV light, which can alter the genetic sequence of skin cells. Which choice below best describes how UV
light might cause skin cancer?
a. UV light changes the genetic code that makes the proteins in the skin cell. The new code
changes the structure and function of these proteins. When the proteins that control cell
growth change in a way that makes them no longer work, cancer is the result.
b. UV light changes the shape of the proteins in the skin cells. These proteins change the
genes in the cell. This makes the cell grow uncontrollably resulting in cancer.
C. UV light makes skin cells grow faster. Overtime, the skin cells adapt to the UV light by
growing faster and faster. Eventually they grow so fast that their growth is no longer
controlled, this results in cancer.
d. None of the above.
