AP Bio Insta-Review Topic 4.6*: Cell Cycle

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to divide and replicate. It includes interphase (G1, S, G2) and the mitotic phase (M).

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are Interphase (G1, S, G2) and the Mitotic phase (M).

Front

What occurs during G1 phase of interphase?

Back

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

Front

What happens during the S phase of interphase?

Back

During the S phase, DNA is replicated, resulting in two sister chromatids for each chromosome.

Front

What is the G2 phase of interphase?

Back

The G2 phase is the final stage 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.

Front

What occurs during prophase?

Back

During prophase, chromosomes condense, become visible, and the nuclear envelope begins to break down.

Front

What happens during metaphase?

Back

During metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres.

Front

What is anaphase?

Back

Anaphase is the phase where sister chromatids are pulled apart to opposite poles of the cell.

Front

What occurs during telophase?

Back

During telophase, the nuclear envelope reforms around each set of chromosomes, which begin to de-condense.
