Mutations are good? How could anyone say this?!?! Mutations are what cause Cancer. Mutations are what cause Alzheimer's and other horrible diseases. Today we’re going to talk about exactly why mutations in the DNA are bad for humans and living organisms. But before we talk about DNA mutations, we have to talk about DNA and cells themselves. The cell is what DNA is located. More specifically, it’s located in the nucleus. Cells are different from organism-to-organism. Some organisms are single-celled so that cell does everything it needs to do to survive, while other organisms are multicelled so each cell does something different. For these organisms, they tend to have cells that split apart to make two new cells. This is called the cell cycle.
