present in the same
cell
- An oncogene is active
(Active oncogene)
- How does it become active
- Both copies of the gene are mutated
- Could be one
copy for an
oncogene
- Both copies of the gene are mutated
- A gene that can turn
a cell into a tumor
cell when active in
the same cell as an
inactive tumor
