Cell Cycle and Mitosis

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through from its formation to its division into two daughter cells.

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).

Front

What occurs during Interphase?

Back

During Interphase, the cell grows, duplicates its DNA, and prepares for mitosis.

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 happens during Prophase?

Back

During Prophase, chromosomes condense, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What happens during Metaphase?

Back

During Metaphase, chromosomes align at the equatorial plane of the cell, and spindle fibers attach to the centromeres.

Front

What happens during Anaphase?

Back

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

Front

What happens during Telophase?

Back

During Telophase, the chromosomes de-condense, the nuclear envelope re-forms, and the cell prepares to divide.

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 significance of the S phase?

Back

The S phase is significant because it is when DNA replication occurs, ensuring that each daughter cell receives an identical set of chromosomes.
