Cell Cycle and Mitosis 2

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 happens during the S phase of the cell cycle?

Back

During the S phase, DNA is replicated, ensuring that each daughter cell receives an identical set of chromosomes.

Front

What is anaphase in mitosis?

Back

Anaphase is the phase in mitosis where chromosomes are pulled apart by spindle fibers to opposite sides of the cell.

Front

What is the longest stage of the cell cycle?

Back

The longest stage of the cell cycle is Interphase, which includes G1, S, and G2 phases.

Front

What occurs during cytokinesis?

Back

Cytokinesis is the process where the cell membrane splits, resulting in the formation of two new daughter cells.

Front

Define Interphase.

Back

Interphase is the phase of the cell cycle where the cell prepares for division, including growth and DNA replication.

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 difference between mitosis and cytokinesis?

Back

Mitosis is the division of the nucleus, while cytokinesis is the division of the cytoplasm and cell membrane.

Front

What happens during prophase?

Back

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

Front

What is the function of the centromere?

Back

The centromere is the region of a chromosome where sister chromatids are joined and where spindle fibers attach during mitosis.
