Cell Cycle and Mitosis

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. It consists of interphase (G1, S, G2) and mitotic phase (M).

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in the duplication of chromosomes.

Front

What is mitosis?

Back

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

Front

What are the main phases of mitosis?

Back

The 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 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.

Front

What occurs during anaphase?

Back

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

Front

What occurs during telophase?

Back

During telophase, chromosomes de-condense back into chromatin, the nuclear envelope re-forms, 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 separate daughter cells.

Front

What is the purpose of mitosis?

Back

The purpose of mitosis is to enable growth, repair damaged tissues, and produce new cells.
