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 of the chromosomes.

Front

What is Anaphase?

Back

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

Front

What happens 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 of a parental cell divides into two daughter cells.

Front

What is the G1 checkpoint?

Back

The G1 checkpoint checks for cell size, nutrients, growth factors, and DNA damage before the cell enters the S phase.

Front

What is the G2 checkpoint?

Back

The G2 checkpoint ensures that all DNA has been replicated correctly and checks for DNA damage before the cell enters mitosis.

Front

What is the M checkpoint?

Back

The M checkpoint ensures that all chromosomes are properly attached to the spindle apparatus before the cell proceeds with mitosis.
