Cell Cycle and Mitosis TR/DATA

Front

What is the G1 phase in the cell cycle?

Back

The G1 phase is the first stage of interphase where the cell grows and synthesizes proteins necessary for DNA replication.

Front

What occurs during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in the duplication of chromosomes.

Front

What is the G2 phase responsible for?

Back

The G2 phase is the second growth phase where the cell prepares for mitosis by producing proteins and organelles.

Front

Define cytokinesis.

Back

Cytokinesis is the process of division of the cytoplasm, resulting in two separate daughter cells after mitosis.

Front

List the phases of mitosis in the correct order.

Back

The correct order of mitosis is: Prophase, Metaphase, Anaphase, Telophase.

Front

What percentage of the cell cycle do cells spend in interphase?

Back

Cells spend approximately 90% of their cycle in interphase.

Front

What is the M phase in the cell cycle?

Back

The M phase, or mitotic phase, is the stage of the cell cycle where mitosis and cytokinesis occur.

Front

What happens during prophase?

Back

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

Front

What is the role of spindle fibers during mitosis?

Back

Spindle fibers help separate the chromosomes and pull them to opposite poles of the cell during mitosis.

Front

What is the significance of the metaphase stage?

Back

In metaphase, chromosomes align at the cell's equatorial plane, ensuring that each daughter cell will receive an identical set of chromosomes.
