Cell Cycle Mitosis #2

Front

What process does a multi-cellular organism use to replace its damaged body cells?

Back

Mitosis is the process used by multi-cellular organisms to replace damaged body cells.

Front

What stage of mitosis is characterized by the separation of sister chromatids?

Back

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

Front

What is the main purpose of mitosis?

Back

The main purpose of mitosis is to ensure that each daughter cell receives an identical set of chromosomes.

Front

What phase of mitosis is shown when the nuclear envelope begins to reform?

Back

Telophase is the phase of mitosis where the nuclear envelope reforms around the separated chromosomes.

Front

Which checkpoint ensures that all DNA has been replicated and is free of errors?

Back

The G2 checkpoint ensures that all DNA has been replicated and checks for errors before mitosis begins.

Front

What are sister chromatids?

Back

Sister chromatids are identical copies of a chromosome, connected by a centromere, formed during DNA replication.

Front

What is the role of spindle fibers during mitosis?

Back

Spindle fibers help separate the sister chromatids and pull them to opposite poles of the cell during mitosis.

Front

What happens during prophase of mitosis?

Back

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

Front

What is the significance of the M phase in the cell cycle?

Back

The M phase is significant because it is the stage where mitosis occurs, leading to the division of the cell into two daughter cells.

Front

What occurs during metaphase of mitosis?

Back

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