The normal function of a tumor suppressor gene is
to produce growth signals
to cause the cell to move faster through the cell cycle
to code for proteins that inhibit, or slow, cell division
to attack cancer cells in the body
Oncogenes
are mutated forms of tumor suppressor genes
are mutated genes the inhibit the cell cycle
are mutated forms of genes that code for proteins that normally assist in apoptosis
are mutated genes that code for proteins which activate cell division too often or at the improper time
