A mutation is a permanent change in the DNA sequence of a gene. Sometimes mutations in DNA can cause changes in the way a cell behaves. This is because genes contain the instructions necessary for a cell to work. If some of the instructions to the cell are wrong, then the cell may not know what it is supposed to do!
There are two ways in which DNA can become mutated:

Slooze Worm Mutagenesis
This activity demonstrates how the DNA of the mythical Slooze worm can acquire a mutation as it grows from a single cell into an eight-celled organism.
