The 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 phases including interphase and mitosis.

Front

What are the main purposes of cell replication?

Back

Cell replication is necessary for growth, repair of damaged tissue, and replacement of dying cells.

Front

What happens during DNA replication?

Back

During DNA replication, the DNA molecule makes a copy of itself, ensuring that each new cell has the same genetic information.

Front

What phase does a cell spend most of its life in?

Back

A cell spends most of its life in Interphase, which is the phase where the cell grows and prepares for division.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.

Front

List the phases of mitosis in the correct order.

Back

The correct order of the phases of mitosis is Prophase, Metaphase, Anaphase, and Telophase.

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 is Metaphase?

Back

Metaphase is the stage of mitosis where chromosomes line up at the cell's equatorial plane, preparing for separation.

Front

What happens during Anaphase?

Back

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

Front

What is Telophase?

Back

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