Control of the Cell Cycle

What happens when a cell dies inside the body and how does the body know when to make new cells? The cell cycle is the series of events that take place as new cells grow and divide. In average this process takes about 24 hours for cells in mammals. This game is rather easy to complete if you are familiar with the different phases in the cell cycle. If you're not, pay extra attention to the image of the cell cycle in the introduction. As "Cell Division Supervisor" inside the cell nucleus, your job is to control cell division to make sure each stage of the cell cycle occurs in the correct order. You also have to ensure the cell has successfully replicated its genetic material at specific checkpoints in the cell cycle. If you make more than three mistakes during one cell division, the cell will be destroyed and you will have to start again.

About the game

The game is about the different phases in ordinary cell division, mitosis. Between each phase there are several "check points" to make sure that nothing happened to the genetic material on the way.

About the educational games

The educational games are based on Nobel Prize awarded achievements and were produced between 2001 and 2012. Most games have not been updated since production (including potential scientific facts changes) and are provided here on an 'as is' basis by popular demand.

Some of the games run in modern browsers without the need of any plugin (either as a new version or using Ruffle), but many of the games still require Adobe Flash Player. Flash is an old technology that has reached end of life. These games will no longer work without a dedicated setup. If you are depending on these games in your profession, please advice your local IT support. We do not have the resources to provide support.

We are working on supporting more games without Flash.
