2.34 Mitosis Flashcard

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 of the chromosomes.

Front

What is anaphase?

Back

Anaphase is the stage of mitosis 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 cell prepares to divide.

Front

What is interphase?

Back

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

Front

What are centrioles?

Back

Centrioles are cylindrical structures that help organize the spindle fibers during cell division.

Front

What are spindle fibers?

Back

Spindle fibers are protein structures that separate chromosomes during mitosis.

Front

What are chromatids?

Back

Chromatids are the two identical halves of a duplicated chromosome, joined at the centromere.
