Using the gas pedal analogy explain the impact on the cell cycle of a proto-oncogene versus an oncogene

Using the gas pedal analogy, the proto-oncogene would be an accelerator since they promote cell division and deregulate apoptosis, while tumor suppressor would be the brakes since they constrain the progress of the cell cycle and induce cell apoptosis. An oncogene is, therefore, when the accelerator is stuck in down position and the brakes are not working.

Using the gas-pedal analogy oncogene, when the accelerator is stuck in down position and the brakes are not working.

Proto-oncogene:

Tumor suppressor genes:

Hence, we can say that oncogene, when the accelerator is stuck in down position and the brakes are not working.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
