The Cell Cycle and Mitosis Review (6th) - Duncan

Front

What is the cell cycle?

Back

The cell cycle is the series of events that take place in a cell leading to its division and duplication (replication). It consists of phases: G1, S, G2, and M.

Front

What happens during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows and synthesizes proteins necessary for DNA replication.

Front

What occurs 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 G2 phase?

Back

The G2 phase is the final phase of interphase where the cell prepares for mitosis, including the synthesis of proteins and organelles.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, involving stages: prophase, metaphase, anaphase, and telophase.

Front

What occurs during prophase?

Back

During prophase, the nuclear membrane breaks down, chromosomes condense, and spindle fibers begin to form.

Front

What is metaphase?

Back

Metaphase is the stage of mitosis where chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres.

Front

What happens during anaphase?

Back

During anaphase, centrioles pull the sister chromatids apart towards opposite sides of the cell.

Front

What is telophase?

Back

Telophase is the final stage of mitosis where the chromosomes de-condense, the nuclear membrane re-forms, and the cell prepares to divide.

Front

What is cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm divides, resulting in two separate daughter cells.
