Mitosis and Cell Cycle Concepts

Front

What is the definition of diploid?

Back

A diploid cell contains two complete sets of chromosomes, one from each parent.

Front

What is the definition of haploid?

Back

A haploid cell contains only one set of chromosomes.

Front

What are the main phases of the cell cycle?

Back

The main phases are Interphase (G1, S, G2) and Mitosis (Prophase, Metaphase, Anaphase, Telophase).

Front

What happens during Prophase?

Back

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

Front

What happens during Metaphase?

Back

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

Front

What happens during Anaphase?

Back

Sister chromatids are pulled apart to opposite poles of the cell.

Front

What happens during Telophase?

Back

Chromatids reach the poles, the nuclear envelope re-forms, and chromosomes begin to de-condense.

Front

What is the purpose of the cell cycle checkpoints?

Back

To ensure that the cell is healthy and to prevent mutations by checking for DNA damage and proper chromosome alignment.

Front

What is cancer in relation to the cell cycle?

Back

Cancer is caused by disruptions in the cell cycle, leading to uncontrolled cell division and the formation of tumors.

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.
