Understanding Cell Cycle and Mitosis

Front

What is the cell cycle?

Back

The cell cycle is a series of phases that a cell goes through to grow and divide, including interphase (G1, S, G2) and mitotic phase (M).

Front

What occurs during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in the duplication of chromosomes.

Front

What is mitosis?

Back

Mitosis is the process of nuclear division in eukaryotic cells that results in two identical daughter cells.

Front

What are the main stages of mitosis?

Back

The main stages of mitosis are prophase, metaphase, anaphase, and telophase.

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 is the role of the spindle apparatus during mitosis?

Back

The spindle apparatus helps to separate sister chromatids and pull them to opposite poles of the cell during anaphase.

Front

Define cytokinesis.

Back

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

Front

What is cleavage furrow formation?

Back

Cleavage furrow formation is the process during cytokinesis in animal cells where the cell membrane pinches inwards to separate the two daughter cells.

Front

What occurs during metaphase?

Back

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

Front

What is anaphase?

Back

Anaphase is the stage of mitosis where sister chromatids are pulled apart to opposite poles of the cell.
