Cell Cycle and Cancer

Front

What is P53?

Back

P53 is a tumor-suppressor gene that helps regulate the cell cycle and prevent cancer.

Front

What are the results of mitosis?

Back

In mitosis, the two resulting cells are identical to the starting cell and identical to each other.

Front

What are telomeres?

Back

Telomeres are regions of DNA at the ends of chromosomes that shorten as cells divide.

Front

What is the longest phase of the cell cycle?

Back

The cell spends most of its life in Interphase.

Front

What is the correct order of mitosis stages?

Back

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

Front

What happens to telomeres as you age?

Back

Telomeres shorten as you age.

Front

What is the role of tumor-suppressor genes?

Back

Tumor-suppressor genes help prevent uncontrolled cell growth and division.

Front

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

Back

The S phase is when DNA synthesis occurs, resulting in the duplication of chromosomes.

Front

What is cytokinesis?

Back

Cytokinesis is the process that divides the cytoplasm of a parental cell into two daughter cells after mitosis.

Front

What is the difference between proto-oncogenes and tumor-suppressor genes?

Back

Proto-oncogenes promote cell division, while tumor-suppressor genes inhibit it.
