C)Promoting apoptosis and allowing programmed cellular "suicide"
D)Opposing suppressor gene products and promoting cell division

Question

Quizplus · Accepted Answer

Cyclins are a group of promitotic proteins produced by specific oncogenes that, upon activation, propel the cell forward through all phases of the reproduction cycle. Normally, the oncogene expression of cyclins is carefully regulated by suppressor gene products, not the other way around. They respond to transcription factors rather than generate them. Cyclins actually work in opposition to apoptosis.
