Cell Cycle & Mitosis

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are Interphase (G1, S, G2) and Mitosis (Prophase, Metaphase, Anaphase, Telophase) followed by Cytokinesis.

Front

What is Interphase?

Back

Interphase is the longest phase of the cell cycle where the cell grows, duplicates its DNA, and prepares for mitosis.

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

What is Anaphase?

Back

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

Front

What happens during Telophase?

Back

During Telophase, chromosomes de-condense back into chromatin, the nuclear envelope re-forms around each set of chromosomes, and the cell prepares to divide.

Front

What is Cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm divides, resulting in two daughter cells.

Front

What is the significance of the G1 phase?

Back

The G1 phase is the first stage of Interphase where the cell grows and synthesizes proteins necessary for DNA replication.

Front

What occurs during the S phase?

Back

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

Front

What is the G2 phase?

Back

The G2 phase is the final stage of Interphase where the cell continues to grow and prepares for mitosis.
