The Cell Cycle

Front

What is the cell cycle?

Back

The cell cycle is a series of phases that a cell goes through as it grows and divides, including interphase and the mitotic phase.

Front

What are the three main stages of interphase?

Back

The three main stages of interphase are G1 (Gap 1), S (Synthesis), and G2 (Gap 2).

Front

What occurs during the G1 phase of interphase?

Back

During the G1 phase, the cell grows, produces RNA, 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 identical sets of chromosomes.

Front

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

Back

The G2 phase involves further growth and preparation 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 are the four main phases of mitosis?

Back

The four main phases of mitosis are prophase, metaphase, anaphase, and telophase.

Front

What occurs during prophase?

Back

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

Front

What is the significance of metaphase in mitosis?

Back

In metaphase, chromosomes align at the cell's equatorial plane, ensuring that each daughter cell will receive an identical set of chromosomes.

Front

Describe anaphase in the context of mitosis.

Back

During anaphase, sister chromatids are pulled apart to opposite poles of the cell by the spindle fibers.
