What is interphase?

Back

Interphase is the phase of the cell cycle where the cell spends most of its time, preparing for division. It consists of three stages: G1 (growth), S (DNA synthesis), and G2 (preparation for mitosis).

Front

In which phase are chromosomes not visible?

Back

Chromosomes are not visible during interphase because they are in the form of chromatin, which is less condensed.

Front

What is the main function of prophase in the cell cycle?

Back

Prophase is the first stage of mitosis where chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.

Front

What happens during metaphase?

Back

During metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres of the chromosomes.

Front

What is anaphase?

Back

Anaphase is the stage of mitosis where sister chromatids are pulled apart to opposite poles of the cell.

Front

Define telophase.

Back

Telophase is the final stage of mitosis where the chromosomes reach the poles, the nuclear envelope re-forms, and the chromosomes begin to de-condense.

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 correct order of the phases of the cell cycle?

Back

The correct order is Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis.

Front

How long does a cell typically spend in interphase?

Back

A cell typically spends about 90% of its life cycle in interphase.

Front

What is the significance of the G1 phase in interphase?

Back

The G1 phase is crucial for cell growth and preparation for DNA replication.
