Cell Cycle and Mitosis

Front

What are the stages of the cell cycle in order?

Back

G1, S, G2, M

Front

What phase of mitosis is characterized by the separation of sister chromatids?

Back

Anaphase

Front

What is the primary cause of cancer related to the cell cycle?

Back

Errors in the regulatory process of the cell cycle that results in uncontrolled cell growth.

Front

How many chromosomes do fruit fly daughter cells have after mitosis if they start with 8 chromosomes?

Back

8 chromosomes.

Front

What is the final stage of mitosis where the cytoplasm divides?

Back

Cytokinesis.

Front

Define the G1 phase of the cell cycle.

Back

The G1 phase is the first gap phase where the cell grows and prepares for DNA replication.

Front

What occurs during the S phase of the cell cycle?

Back

DNA replication occurs, resulting in two sister chromatids for each chromosome.

Front

What is the role of the G2 phase in the cell cycle?

Back

The G2 phase is the second gap phase where the cell prepares for mitosis, checking for DNA damage and ensuring all DNA is replicated.

Front

What happens during prophase of mitosis?

Back

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

Front

What is metaphase in mitosis?

Back

Metaphase is the stage where chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres.
