Biology Cell Cycle, Cancer, & Mitosis

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What are the phases of the cell cycle?

Back

The cell cycle consists of interphase (G1, S, G2) and the mitotic phase (mitosis and cytokinesis).

Front

What happens during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows and carries out normal functions, with a normal amount of DNA.

Front

What is the S-phase in the cell cycle?

Back

The S-phase is the part of interphase where DNA is replicated, resulting in double the amount of DNA.

Front

What is interphase?

Back

Interphase is the period of the cell cycle when the cell is not dividing, and it includes G1, S, and G2 phases.

Front

What is cytokinesis?

Back

Cytokinesis is the final stage of cell division where the cytoplasm divides, resulting in two separate daughter cells.

Front

Why is DNA replication important before cell division?

Back

DNA replication is crucial to ensure that each daughter cell receives an identical set of genetic information.

Front

What is cancer in relation to the cell cycle?

Back

Cancer is a disease characterized by uncontrolled cell division, often due to mutations in genes that regulate the cell cycle.

Front

What is the role of checkpoints in the cell cycle?

Back

Checkpoints are regulatory mechanisms that ensure the cell cycle progresses only when certain conditions are met, preventing errors.

Front

What occurs during prophase in mitosis?

Back

During prophase, chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and spindle fibers begin to form.
