STUDY GUIDE: Cell Cycle

Front

What is chromatin?

Back

Chromatin is the relaxed form of DNA found during most of interphase, allowing for gene expression and DNA replication.

Front

What is cytokinesis?

Back

Cytokinesis is the stage of the cell cycle where the rest of the cell divides after mitosis is complete, resulting in two separate cells.

Front

What occurs during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows and develops, preparing for DNA replication.

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in the duplication of chromosomes.

Front

What is the role of spindle fibers during cell division?

Back

Spindle fibers separate chromosomes to opposite poles of the cell during mitosis.

Front

What is the significance of the centromere?

Back

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

Front

What occurs during prophase?

Back

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

Front

What happens during metaphase?

Back

During metaphase, chromosomes line up at the equator of the cell, preparing for separation.

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, resulting in two separate cells.

Front

What is the purpose of checkpoints in the cell cycle?

Back

Checkpoints in the cell cycle ensure that the cell is ready to proceed to the next phase, preventing errors in cell division.
