cell cycle and mitosis

Front

What is the G1 phase of 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 is replicated, resulting in two identical sets of chromosomes.

Front

What is the M phase in the cell cycle?

Back

The M phase is the stage of the cell cycle where mitosis and cytokinesis occur, leading to cell division.

Front

What are the four stages of mitosis?

Back

The four stages of mitosis are prophase, metaphase, anaphase, and telophase.

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 cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm divides, resulting in two separate daughter cells.

Front

What is the role of spindle fibers during mitosis?

Back

Spindle fibers help separate the chromosomes during mitosis by attaching to the centromeres and pulling them apart.

Front

What is the significance of the G2 phase?

Back

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

Front

How does the cell cycle ensure proper cell division?

Back

The cell cycle includes checkpoints that monitor the cell's progress and ensure that conditions are favorable for division.

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.
