Cell Cycle + Mitosis

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through from its formation to its division into two daughter cells. It includes interphase (G1, S, G2) and mitotic phase (mitosis and cytokinesis).

Front

What happens during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows, matures, and carries on normal metabolic activities. It prepares for DNA replication.

Front

What is the S phase in the cell cycle?

Back

The S phase (Synthesis phase) is the part of interphase where DNA is replicated, resulting in two copies of each chromosome.

Front

What occurs during the G2 phase of the cell cycle?

Back

During the G2 phase, the cell continues to grow and prepares for mitosis by producing proteins and organelles.

Front

What is mitosis?

Back

Mitosis is the process of nuclear division in eukaryotic cells that results in two identical daughter nuclei, each with the same number of chromosomes as the parent cell.

Front

What are the stages of mitosis?

Back

The stages of mitosis 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 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 occurs during anaphase?

Back

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

Front

What is telophase?

Back

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