Cell Cycle Practice Flashcard

Front

What are cyclins?

Back

Cyclins are a family of closely related proteins that regulate the cell cycle.

Front

What phase of the cell cycle is characterized by the separation of sister chromatids?

Back

Telophase/Cytokinesis.

Front

What is the primary purpose of mitosis?

Back

The primary purpose of mitosis is the division of the nucleus.

Front

What do cancer cells form?

Back

Cancer cells form masses of cells called tumors.

Front

What are sister chromatids?

Back

Sister chromatids are identical copies of a chromosome connected by a centromere.

Front

What is the role of the centromere?

Back

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

Front

What happens during interphase?

Back

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

Front

What is cytokinesis?

Back

Cytokinesis is the process where the cytoplasm of a parental cell divides into two daughter cells.

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.

Front

What are growth factors?

Back

Growth factors are proteins that stimulate cell division and growth.
