Mutation

Okay, so you know how all living things have tiny things inside called cells? And in those cells, there are little things called genes that tell your body how to grow and work? Well, sometimes those genes can change or have mistakes in them. That's called a mutation.

Think of it like when you build a tower out of blocks. Each block is like a gene. But sometimes, when you build, you accidentally put the wrong block in the wrong spot. That's like a mutation.

Sometimes, mutations can be good, like when they make you stronger or faster. But sometimes, they can be bad, like when they make you sick or give you problems.

Mutations happen all the time, but most of the time, they don't really matter. They're just part of life. But scientists study mutations to learn more about how living things work and how they change over time.
