Front

What is the primary purpose of mitosis in multicellular organisms?

Back

To repair and replace damaged cells.

Front

What occurs during prophase of mitosis?

Back

The chromatin condenses, spindle fibers form, and the nuclear membrane breaks apart.

Front

What is the cell cycle?

Back

The series of events that take place in a cell leading to its division and duplication.

Front

What are the main phases of the cell cycle?

Back

Interphase, mitosis, and cytokinesis.

Front

What happens during interphase?

Back

The cell grows, duplicates its DNA, and prepares for mitosis.

Front

What is cytokinesis?

Back

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