The Cell Cycle

Front

What are the main stages of the cell cycle?

Back

The main stages of the cell cycle are Interphase (which includes G1, S, and G2 phases) and the Mitotic phase (which includes mitosis and cytokinesis).

Front

What happens during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows and carries out normal functions while preparing for DNA replication.

Front

What occurs during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in two identical sets of chromosomes.

Front

What is the role of the G2 phase in the cell cycle?

Back

The G2 phase is a period of further growth and preparation for mitosis, where the cell checks for DNA damage and ensures all DNA is replicated.

Front

What is mitosis?

Back

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

Front

List the stages of mitosis in order.

Back

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

Front

What happens during prophase?

Back

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

Front

What occurs during metaphase?

Back

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

Front

Describe anaphase in mitosis.

Back

In anaphase, sister chromatids are pulled apart by spindle fibers and move toward opposite poles of the cell.

Front

What is telophase?

Back

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