Cell cycle, mitosis, and cancer

Front

What are the main stages of the cell cycle?

Back

The main stages of the cell cycle are Interphase (G1, S, G2) and Mitotic Phase (M).

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.

Front

What is the significance of Metaphase in mitosis?

Back

In Metaphase, chromosomes align at the cell's equatorial plane, ensuring that each daughter cell will receive an identical set of chromosomes.

Front

What happens during Anaphase?

Back

During Anaphase, sister chromatids are pulled apart to opposite poles of the cell.

Front

What is the role of the cell cycle in an organism?

Back

The cell cycle is essential for the growth of an organism and the repair of damaged tissues.

Front

How does cancer affect the cell cycle?

Back

Cancer disrupts the normal regulation of the cell cycle, leading to uncontrolled cell division and the formation of tumors.

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 the purpose of the G1 phase in the cell cycle?

Back

The G1 phase is a period of cell growth and preparation for DNA replication.

Front

What occurs during the S phase of the cell cycle?

Back

During the S phase, DNA is replicated, resulting in two identical sets of chromosomes.

Front

What is the function of the G2 phase?

Back

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