Cell Cycle

Front

What is the cell cycle?

Back

The cell cycle is the series of events that take place in a cell leading to its division and duplication (replication). It consists of interphase and the mitotic phase.

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are Interphase (G1, S, G2) and the Mitotic phase (Mitosis and Cytokinesis).

Front

What happens during Interphase?

Back

During Interphase, the cell grows, performs its normal functions, and duplicates its DNA in preparation for cell division.

Front

What is Mitosis?

Back

Mitosis is the process of cell division where one cell divides to produce two identical daughter cells.

Front

What is Cytokinesis?

Back

Cytokinesis is the final step of cell division where the cytoplasm of a parental cell is divided into two daughter cells.

Front

What occurs during Prophase?

Back

During Prophase, the 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 line up at the cell's equatorial plane, and spindle fibers attach to the centromeres of the chromosomes.

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 occurs during Telophase?

Back

During Telophase, the chromosomes reach the poles, begin to de-condense back into chromatin, and the nuclear envelope re-forms around each set of chromosomes.

Front

What is the S phase of Interphase?

Back

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