Mitosis
The phase where chromosomes line up down the middle of the cell.
What is Metaphase?
A group of molecules that can phosphorylate and activate proteins to regulate the cell cycle.
What are CDKs?
The number of chromatids in a replicated chromosome.
What is 2?
The checkpoint of the cell cycle that verifies the spindle fibers are attached correctly.
What is the Spindle checkpoint?
The two major phases of the cell cycle?
What are Interphase and M Phase?
The phase where sister chromatids are pulled apart.
What is Anaphase?
Genes that scientists compare to the brake pedal of a car.
What is a tumor suppressor gene?
The form of DNA at the beginning of Telophase?
What is a chromosome?
Occurs when a cell is damaged or not needed.
What is apoptosis?
What are G1, S, & G2?
The phase where DNA condenses to form visible chromosomes.
What is prophase?
The cyclin-CDK complex used at the G2 checkpoint prior to mitosis.
What is MPF?
One half of a replicated chromosome.
What is a sister chromatid?
The result of uncontrolled cell growth.
What is cancer?
The part of the cell cycle where the cell spends the majority of its time.
What is Interphase?
The phase where two nuclei are present in one cell.
What is Telophase?
The mutated form of proto-oncogenes.
What are oncogenes?
The structure of DNA during Interphase.
What is chromatin?
Checkpoint that verifies that DNA has been replicated correctly.
What is the G2 checkpoint.
The phase when DNA is replicated.
What is S phase?
The 4 phases of mitosis in order.
What is Prophase, Metaphase, Anaphase, & Telophase.
A family of proteins that control the progression of cells through the cell cycle by activating cyclin-dependent kinase (Cdk) enzymes.
What is a cyclin?
The phase of mitosis when the number of chromosomes doubles?
What is anaphase?
Cells that don't divide go to this step.
What is G0 phase?
The part of the cell cycle when the nucleus divides.
