The following diagram shows the mitotic process.

A parent cell is shown on the left. The nucleus and chromosomes are labeled. An arrow points to two daughter cells on the right. The arrow is labeled DNA replication, then mitosis.

What is a limitation of this diagram?

It does not show senescence. It only shows the interphase portion of mitosis.

Use the image to answer the question.

The cell cycle begins with interphase, where the cell takes approximately 10 hours to grow. If it passes the G1 checkpoint, the DNA duplication starts and goes on for approximately eight hours. The cell further grows for approximately four hours. After passing the G2 checkpoint, the process of mitosis takes place, which takes approximately one to two hours. The phases during mitosis are prophase, metaphase, anaphase, telophase, and cytokinesis. After cytokinesis, the daughter cells enter interphase, and the cycle gets repeated.

According to the figure, mitosis occurs after which stage in the cell cycle?
