Mitosis and Cell Cycle

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 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 Interphase?

Back

During the G1 phase, the cell grows and performs its normal functions.

Front

What happens during the S phase of Interphase?

Back

During the S phase, DNA replication occurs, resulting in two copies of each chromosome.

Front

What is the role of the spindle fibers during Mitosis?

Back

Spindle fibers help separate the sister chromatids and pull them toward opposite poles of the cell.

Front

What is Cytokinesis?

Back

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

Front

What happens during Prophase?

Back

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

Front

What occurs during Metaphase?

Back

During Metaphase, chromosomes line up in the middle of the cell and attach to spindle fibers.

Front

What is Anaphase?

Back

Anaphase is the stage of Mitosis where sister chromatids separate and move toward opposite poles of the cell.

Front

What happens during Telophase?

Back

During Telophase, the chromosomes reach the poles, the nuclear envelope re-forms around each set of chromosomes, and the chromosomes begin to de-condense.
