Cell Cycle Mitosis #2

Front

What process does a multi-cellular organism use to replace its damaged body cells?

Back

Mitosis is the process used by multi-cellular organisms to replace damaged body cells.

Front

What is the structure that holds sister chromatids together?

Back

The centromere is the structure that holds sister chromatids together.

Front

In which stage of the cell cycle do cells spend 90% of their time?

Back

Cells spend 90% of their time in Interphase.

Front

Is cytokinesis the first stage of mitosis?

Back

False, cytokinesis is not the first stage of mitosis; it occurs after mitosis.

Front

How does chromosome duplication occur in mitosis?

Back

DNA is replicated during the S phase of the cell cycle to form identical sister chromatids.

Front

What are sister chromatids?

Back

Sister chromatids are identical copies of a chromosome, connected by a centromere.

Front

What is the role of mitosis in growth and development?

Back

Mitosis allows for growth, development, and tissue repair in multi-cellular organisms.

Front

What happens during prophase of mitosis?

Back

During prophase, chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.

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 the formation of sister chromatids.

Front

What occurs during metaphase of mitosis?

Back

During metaphase, chromosomes align at the cell's equatorial plane, preparing for separation.
