Mitosis, Cell Cycle and Cancer

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 are the stages of the cell cycle?

Back

The cell cycle consists of interphase (G1, S, G2) and the mitotic phase (mitosis and cytokinesis).

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, DNA is replicated, resulting in two copies of each chromosome.

Front

What is a chromosome?

Back

A chromosome is a structure made of DNA and protein that contains genetic information.

Front

What is a chromatid?

Back

A chromatid is one half of a duplicated chromosome, which is joined to its sister chromatid by a centromere.

Front

What is cytokinesis?

Back

Cytokinesis is the final stage of cell division where the cytoplasm divides, resulting in two separate daughter cells.

Front

What is the role of centrioles in mitosis?

Back

Centrioles help organize the spindle fibers that separate chromosomes during mitosis.

Front

What is cancer in relation to cell division?

Back

Cancer is a disease characterized by uncontrolled cell division, leading to the formation of tumors.

Front

What are mutations?

Back

Mutations are changes in the DNA sequence that can lead to changes in protein function and may contribute to cancer.

Front

What occurs during prophase?

Back

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