Once upon a time, in a bustling city called Cellville, there lived a group of cells who were responsible for maintaining the harmony and balance of the city. These cells were known as the Mitos, and they were in charge of cell division, ensuring that everything ran smoothly.

The Mitos had a special power - they could divide themselves into two identical daughter cells. This process was called mitosis, and it was crucial for the growth and repair of the city. The Mitos knew that they had to be responsible and make sure that each division was perfect.

But the Mitos also understood that they couldn't divide all the time. They needed some rest too. So, after each division, they would enter a phase called interphase. During interphase, they would relax and prepare for the next round of division.

The Mitos knew that their actions were regulated by a molecular control system, which acted like a traffic light, ensuring that everything happened at the right time. This control system made sure that the Mitos didn't divide too much or too little, maintaining the balance in Cellville.

One day, a young Mito named Max started feeling lazy. He didn't want to divide anymore and thought he could just skip interphase and keep dividing endlessly. Max ignored his responsibilities and started causing chaos in Cellville.
