What are the genes involved in regulating the cell cycle? What are their functions?

Question 1

Proto-oncogenes

Answer 1

Promote cell division and growth. Mutations can turn them into oncogenes, leading to uncontrolled division.

Question 2

tumor suppressor genes

Answer 2

Slow down cell division, repair DNA mistakes, or trigger cell death if needed. Mutations can disable these functions, leading to cancer.

Question 3

Cyclone and CDKs

Answer 3

Control the timing and progression of the cell cycle.
