Cell cycle, mitosis, and cancer

Front

What is a chromosome?

Back

A chromosome is DNA tightly coiled around proteins, which carries genetic information.

Front

What happens during the S stage of interphase?

Back

During the S stage of interphase, the DNA is replicated.

Front

What is a chromatid?

Back

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

Front

What are chromatids?

Back

Chromatids are the two exact copies of DNA in a chromosome.

Front

What is the purpose of the cell cycle?

Back

The purpose of the cell cycle is the growth of an organism and the repair of damaged tissue.

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division, including DNA replication.

Front

What is mitosis?

Back

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

Front

What are the stages of mitosis?

Back

The stages of mitosis are prophase, metaphase, anaphase, and telophase.

Front

What is the role of the centromere?

Back

The centromere is the region of a chromosome where the two sister chromatids are joined together.

Front

What is cancer in relation to the cell cycle?

Back

Cancer is a disease characterized by uncontrolled cell division, often due to mutations in genes that regulate the cell cycle.
