Mitosis

Front

What is mitosis?

Back

Mitosis is the process of cell division in which a single cell divides to produce two identical daughter cells, each with the same number of chromosomes as the original cell.

Front

What is the primary purpose of mitosis in multi-cellular organisms?

Back

The primary purpose of mitosis in multi-cellular organisms is to replace damaged or dead cells, allowing for growth and tissue repair.

Front

What are the main stages of the cell cycle?

Back

The main stages of the cell cycle are interphase, mitosis, and cytokinesis.

Front

What occurs during interphase?

Back

During interphase, the cell grows, duplicates its DNA, and prepares for mitosis.

Front

What is cytokinesis?

Back

Cytokinesis is the final stage of cell division where the cytoplasm of a parental cell is divided into two daughter cells.

Front

What happens 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 a chromosome?

Back

A chromosome is a structure made of DNA and protein that contains genetic information; it is visible during cell division.

Front

What is the role of spindle fibers in mitosis?

Back

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

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes with half the number of chromosomes.

Front

What is the significance of the G1 phase in the cell cycle?

Back

The G1 phase is significant because it is the first growth phase where the cell increases in size and synthesizes proteins necessary for DNA replication.
