AP Biology - Cell Cycle

Front

What is the cell cycle?

Back

The cell cycle is a series of phases that a cell goes through to grow and divide, including G1, S, G2, and M phases.

Front

What occurs during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows and doubles its content in preparation for DNA replication.

Front

What is the S phase of the cell cycle?

Back

The S phase is the part of the cell cycle where DNA replication occurs, resulting in two identical sets of chromosomes.

Front

What happens during the G2 phase?

Back

In the G2 phase, the cell continues to grow and prepares for mitosis, ensuring all DNA is replicated and undamaged.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells.

Front

What are the stages of mitosis?

Back

The stages of mitosis are prophase, metaphase, anaphase, and telophase.

Front

What occurs during prophase?

Back

During prophase, chromatin condenses into visible chromosomes, the nuclear membrane breaks down, and spindle fibers begin to form.

Front

What is the role of spindle fibers during mitosis?

Back

Spindle fibers help separate sister chromatids and pull them to opposite poles of the cell during anaphase.

Front

What happens during anaphase?

Back

During anaphase, sister chromatids are pulled apart and move toward opposite ends of the cell.

Front

What is cytokinesis?

Back

Cytokinesis is the final step of cell division where the cytoplasm divides, resulting in two separate daughter cells.
