The Cell Cycle

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, including interphase (G1, S, G2) and mitosis.

Front

What occurs during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows and synthesizes proteins necessary for DNA replication.

Front

What happens during the S phase of the cell cycle?

Back

During the S phase, DNA is replicated, resulting in two identical sets of chromosomes.

Front

What is the purpose of the G2 phase?

Back

The G2 phase is where the cell prepares for mitosis by producing proteins and organelles needed for cell division.

Front

What are the stages of mitosis in order?

Back

The stages of mitosis in order are Prophase, Metaphase, Anaphase, and Telophase.

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 occurs during metaphase?

Back

During metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres.

Front

What happens in anaphase?

Back

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

Front

What is telophase?

Back

Telophase is the final stage of mitosis where chromosomes de-condense, and the nuclear envelope re-forms around each set of chromosomes.

Front

What must be copied before a cell can divide?

Back

Before a cell can divide, its DNA must be copied.
