What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are Interphase (G1, S, G2) and Mitosis (Prophase, Metaphase, Anaphase, Telophase) followed by Cytokinesis.

Front

What occurs during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows in size, synthesizes mRNA and proteins, and prepares for DNA replication.

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in the duplication of chromosomes.

Front

What is the role of the G2 phase in the cell cycle?

Back

The G2 phase involves further growth and preparation for mitosis, including the synthesis of proteins necessary for cell division.

Front

What is Mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, involving phases: Prophase, Metaphase, Anaphase, and Telophase.

Front

What is Cytokinesis?

Back

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

Front

What is the significance of the Metaphase stage in mitosis?

Back

In Metaphase, sister chromatids line up along the equatorial plane of the cell, ensuring proper separation during Anaphase.

Front

How is cancer related to the cell cycle?

Back

Cancer is characterized by uncontrolled cell growth and division, often due to mutations that disrupt normal cell cycle regulation.

Front

What is the difference between benign and malignant tumors?

Back

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

Front

What is apoptosis?

Back

Apoptosis is the process of programmed cell death that occurs in multicellular organisms, playing a crucial role in development and maintaining tissue homeostasis.
