Mitosis

Front

What is Mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.

Front

What are the main phases of Mitosis?

Back

The main phases of Mitosis are Prophase, Metaphase, Anaphase, and Telophase.

Front

What happens during Prophase?

Back

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

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 the role of the centromere?

Back

The centromere is the region of a chromosome where the two sister chromatids are joined and where the spindle fibers attach during cell division.

Front

What happens during Anaphase?

Back

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

Front

What occurs during Telophase?

Back

During Telophase, the chromosomes de-condense back into chromatin, the nuclear envelope re-forms around each set of chromosomes, and the spindle apparatus disassembles.

Front

What is Cytokinesis?

Back

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

Front

Why is DNA replication important before cell division?

Back

DNA replication is important before cell division to ensure that each daughter cell receives an identical set of genetic information.

Front

What is Interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division, including DNA replication during the Synthesis phase.
