Cell Cycle and Mitosis

Front

What is cytokinesis?

Back

Cytokinesis is the division of the cytoplasm during cell division, resulting in two separate daughter cells.

Front

What phase of mitosis involves chromosomes lining up at the equatorial plane?

Back

Metaphase is the phase of mitosis where chromosomes line up at the equatorial plane of the cell.

Front

What are the three phases of interphase?

Back

The three phases of interphase are G1 (Gap 1), S (Synthesis), and G2 (Gap 2).

Front

What occurs during anaphase?

Back

During anaphase, sister chromatids are pulled apart to opposite poles of the cell.

Front

What is the role of the nuclear envelope during prophase?

Back

During prophase, the nuclear envelope begins to break down, allowing the chromosomes to condense and become visible.

Front

How many chromosomes are present in the daughter cells after mitosis in a diploid human cell?

Back

After mitosis, each daughter cell contains 46 chromosomes, the same number as the original diploid cell.

Front

What is the significance of the S phase in the cell cycle?

Back

The S phase is significant because it is when DNA replication occurs, resulting in two copies of each chromosome.

Front

What is the main event of telophase?

Back

During telophase, the chromosomes begin to de-condense, and the nuclear envelope re-forms around each set of chromosomes.

Front

What is the difference between mitosis and cytokinesis?

Back

Mitosis is the process of nuclear division, while cytokinesis is the division of the cytoplasm that follows mitosis.

Front

What happens during G1 phase of the cell cycle?

Back

During G1 phase, the cell grows and carries out normal metabolic processes.
