Unit 5 flashcard 1

Front

What is the first phase of mitosis?

Back

Prophase

Front

During which phase of mitosis do the sister chromatids separate?

Back

Anaphase

Front

What is the process called when the cytoplasm divides after mitosis?

Back

Cytokinesis

Front

What is the main purpose of mitosis?

Back

To divide the cell's nucleus and ensure each daughter cell receives an identical set of chromosomes.

Front

What are the four main phases of mitosis?

Back

Prophase, Metaphase, Anaphase, Telophase.

Front

What happens during prophase?

Back

Chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What occurs during metaphase?

Back

Chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres.

Front

What is the role of spindle fibers during mitosis?

Back

To help separate the sister chromatids and pull them to opposite poles of the cell.

Front

What is the difference between mitosis and cytokinesis?

Back

Mitosis is the division of the nucleus, while cytokinesis is the division of the cytoplasm.

Front

What is the significance of the cell cycle?

Back

It regulates cell growth, DNA replication, and cell division.
