The Cell Cycle R

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 phases including interphase and mitosis.

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division. It includes G1 (growth), S (synthesis of DNA), and G2 (preparation for mitosis) phases.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells. It includes stages: prophase, metaphase, anaphase, and telophase.

Front

What is cytokinesis?

Back

Cytokinesis is the final stage of the cell cycle where the cytoplasm of a parental cell divides into two daughter cells.

Front

What is a centromere?

Back

A centromere is the region of a chromosome where the two sister chromatids are joined together and where the spindle fibers attach during cell division.

Front

What are sister chromatids?

Back

Sister chromatids are two identical copies of a single chromosome that are connected by a centromere.

Front

What are centrioles?

Back

Centrioles are cylindrical structures that play a role in cell division by helping to organize the mitotic spindle.

Front

What is prophase?

Back

Prophase is the first stage of mitosis where chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.

Front

What is metaphase?

Back

Metaphase is the stage of mitosis where chromosomes line up at the cell's equatorial plane, and spindle fibers attach to the centromeres.

Front

What is anaphase?

Back

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