Cell Cycle and Mitosis

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, including interphase and the mitotic phase.

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis).

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, DNA is replicated, resulting in two identical sets of chromosomes.

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, chromosomes condense and become visible, the nuclear envelope breaks down, and spindle fibers begin to form.

Front

What is anaphase?

Back

Anaphase is the stage in mitosis where sister chromatids are pulled apart to opposite sides of the cell.

Front

What is the longest stage of the cell cycle?

Back

The longest stage of the cell cycle is interphase.

Front

Why do cells divide instead of just growing larger?

Back

Cells divide to maintain an efficient surface area-to-volume ratio, allowing for adequate nutrient intake and waste removal.

Front

How many chromosomes do humans have?

Back

Humans have 46 chromosomes.
