4.3: Mitosis, Cell Cycle, & Differentiation

Front

What are the three main stages of the cell cycle?

Back

Interphase, Mitosis, Cytokinesis.

Front

What occurs during Interphase?

Back

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

Front

What is the purpose of mitosis?

Back

To divide the cell's nucleus and distribute the duplicated chromosomes into two daughter cells.

Front

What is cytokinesis?

Back

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

Front

What happens during the G1 phase of the cell cycle?

Back

The cell grows and performs normal functions.

Front

What happens during the S phase of the cell cycle?

Back

DNA replication occurs, resulting in two copies of each chromosome.

Front

What happens during the G2 phase of the cell cycle?

Back

The cell continues to grow and prepares for mitosis.

Front

What is the M phase of the cell cycle?

Back

The phase where mitosis and cytokinesis occur.

Front

What are spindle fibers?

Back

Structures that help separate sister chromatids during cell division.

Front

What occurs during prophase?

Back

Chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.
