What is the first stage of mitosis?

Back

Prophase is the first stage of mitosis, where chromatin condenses into visible chromosomes and the nuclear envelope begins to break down.

Front

What is the second stage of mitosis?

Back

Metaphase is the second stage of mitosis, characterized by the alignment of chromosomes along the metaphase plate.

Front

What is the third stage of mitosis?

Back

Anaphase is the third stage of mitosis, during which sister chromatids are pulled apart to opposite poles of the cell.

Front

What is the fourth phase of mitosis?

Back

Telophase is the fourth phase of mitosis, where the chromosomes de-condense and the nuclear envelope re-forms around each set of chromosomes.

Front

Define mitosis.

Back

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

Front

What is the role of spindle fibers in mitosis?

Back

Spindle fibers are structures that help separate chromosomes during mitosis by attaching to the centromeres and pulling them apart.

Front

What happens during prophase?

Back

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

Front

What is the significance of metaphase in mitosis?

Back

Metaphase ensures that chromosomes are properly aligned and attached to spindle fibers, which is crucial for accurate chromosome separation.

Front

What occurs during anaphase?

Back

During anaphase, the sister chromatids are separated and moved to opposite ends of the cell, ensuring each daughter cell will receive an identical set of chromosomes.

Front

What changes occur in telophase?

Back

In telophase, the chromosomes begin to de-condense, the nuclear envelope re-forms, and the cell prepares to divide into two.
