What is the cell cycle?

Back

The cell cycle is the series of events that take place in a cell leading to its division and replication. It consists of interphase (G1, S, G2 phases) and mitosis.

Front

What occurs during interphase?

Back

During interphase, the cell grows, performs its normal functions, and prepares for division. This includes DNA replication in the S phase.

Front

What is mitosis?

Back

Mitosis is the stage of the cell cycle where the cell divides its nucleus and contents, resulting in two daughter cells.

What is cancer?

Back

Cancer is an uncontrolled growth and division of cells, often leading to the formation of tumors.

Front

What is the S phase of the cell cycle?

Back

The S phase (synthesis phase) is the part of interphase where DNA replication occurs, resulting in two identical copies of the DNA.

Front

What triggers the formation of a tumor?

Back

A mutation in a gene that codes for a protein regulating cell division can trigger the formation of a tumor.

Front

What is the role of checkpoints in the cell cycle?

Back

Checkpoints are regulatory pathways that ensure the cell cycle progresses correctly and that any DNA damage is repaired before division.

Front

What is apoptosis?

Back

Apoptosis is the process of programmed cell death that eliminates damaged or unnecessary cells, playing a crucial role in maintaining healthy tissue.

Front

What is the difference between benign and malignant tumors?

Back

Benign tumors are non-cancerous growths that do not spread, while malignant tumors are cancerous and can invade nearby tissues and spread to other parts of the body.

Front

What is DNA replication?

Back

DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule, essential for cell division.
