cell cycle and cell division

Front

What is the cell cycle?

Back

The cell cycle is the series of events that take place in a cell leading to its division and duplication (replication). It consists of interphase and the mitotic phase.

Front

What are the main stages of the cell cycle?

Back

The main stages of the cell cycle are Interphase (G1, S, G2) and the Mitotic phase (Mitosis and Cytokinesis).

Front

What occurs during Interphase?

Back

During Interphase, the cell grows, duplicates its DNA, and prepares for division. It consists of G1 (growth), S (DNA synthesis), and G2 (preparation for mitosis).

Front

What is Mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, involving stages: prophase, metaphase, anaphase, and telophase.

Front

What is Cytokinesis?

Back

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

Front

What happens during Prophase?

Back

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

Front

What happens during Metaphase?

Back

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

Front

What happens during Anaphase?

Back

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

Front

What happens during Telophase?

Back

During Telophase, chromosomes de-condense back into chromatin, the nuclear envelope re-forms around each set of chromosomes, and the cell prepares to divide.

Front

What is Meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse gametes.
