Front

What is the purpose of the cell cycle in the human body?

Back

The cell cycle ensures that our body’s cells grow and repair themselves.

Front

In which phase of the cell cycle does DNA replication occur?

Back

A pair of similar chromosomes.

Front

What is the role of DNA in the cell cycle?

Back

DNA carries the genetic information necessary for cell function and replication.

Front

What is the significance of the G1 phase in the cell cycle?

Back

The G1 phase is where the cell grows and prepares for DNA synthesis.

Front

What happens during the G2 phase of the cell cycle?

Back

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells.
