What is Mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell, essential for growth and repair.

Front

What are the stages of Mitosis?

Back

The stages of Mitosis are Prophase, Metaphase, Anaphase, and Telophase.

Front

What happens during Prophase?

Back

During Prophase, the chromatin condenses into visible chromosomes, the nucleolus disappears, and the mitotic spindle begins to form.

Front

What occurs in Metaphase?

Back

In Metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to kinetochores.

Front

What is Anaphase characterized by?

Back

Anaphase is characterized by the separation of sister chromatids, which are pulled toward opposite poles of the cell.

Front

What happens during Telophase?

Back

During Telophase, the chromosomes de-condense, nuclear envelopes reform around each set of chromosomes, resulting in two nuclei.

Front

What is Cytokinesis?

Back

Cytokinesis is the process that follows Mitosis, where the cytoplasm divides, resulting in two separate daughter cells.

Front

What is the role of checkpoints in the cell cycle?

Back

Checkpoints are regulatory pathways that ensure the cell cycle progresses correctly, preventing errors in DNA replication and division.

Front

What is the significance of the M phase checkpoint?

Back

The M phase checkpoint ensures that all chromosomes are properly attached to the spindle apparatus before proceeding to Anaphase.

Front

What is apoptosis?

Back

Apoptosis is a programmed cell death process that eliminates damaged or unnecessary cells in a controlled manner.
