| Question | Answer |
|---|---|
| An arrest in the cell cycle for repair | Check point |
| Encodes gene products that inhibit unregulated cell division. Mutant alleles function recessively in promotion of a cancerous phenotype in a cell | Tumor suppressor gene |
| Molecule that affects cell proliferation. Generally stimulate proliferation by associating with receptor proteins on the affected cell | Growth factor |
| Programmed cell death in which the cell coordinates its own DNA degradation and nuclear condensation | Apoptosis |
| Normal gene regulating cell proliferation that can become an oncogene when mutated | Proto-oncogene |
| Steroids, peptides, and proteins that act over short and long distances to provide extracellular signals to cells. | Hormones |
| Proteins that underlie the inner surface of the nuclear membrane and become soluble during mitosis to allow dissolution of the nuclear membrane into vesicles | Nuclear lamins |
| The relaying of a signal through the cytoplasm to the nucleus in order to mediate a cellular response to an extracellular signal. | Signal transduction |
| A family of proteins that phosphorylate specific substrates in response to a cell-cycle dependent association with specific cyclins. | Cyclin-dependent kinase |
| Mutant allele of a proto-oncogene that acts dominantly to promote a cancerous phenotype | Oncogene |
