Cell Division: Mitosis and Meiosis

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse daughter cells, each with half the number of chromosomes of the parent cell.

Front

How many chromosomes do daughter cells have after meiosis if the parent cell has 100 chromosomes?

Back

50 chromosomes.

Front

What is the role of DNA replication in the cell cycle?

Back

DNA replication occurs during the S phase of interphase, ensuring that each daughter cell receives an identical set of chromosomes.

Front

What are the stages of mitosis in order?

Back

Prophase, Metaphase, Anaphase, Telophase, Cytokinesis.

Front

What is nondisjunction?

Back

Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during cell division, leading to cells with an abnormal number of chromosomes.

Front

What can cause cancer at the cellular level?

Back

Cancer is often caused by mutations in DNA that disrupt normal cell growth and division.

Front

What happens during prophase of mitosis?

Back

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

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 of the chromosomes.

Front

What is the outcome of anaphase in mitosis?

Back

During anaphase, sister chromatids are pulled apart to opposite poles of the cell, ensuring each daughter cell will receive an identical set of chromosomes.
