Genetic mutations are changes to your DNA sequence that happen during cell division when your cells make copies of themselves. Your DNA tells your body how to form and function. Genetic mutations could lead to genetic conditions like cancer, or they could help humans better adapt to their environment over time. Overview What are genetic mutations? A genetic mutation is a change in a sequence of your DNA. Your DNA sequence gives your cells the information they need to perform their functions. If part of your DNA sequence is in the wrong place, isn’t complete or is damaged, you might experience symptoms of a genetic condition. When do genetic mutations happen? Genetic mutations occur during cell division when your cells divide and replicate. There are two types of cell division: • Mitosis: The process of making new cells for your body. During mitosis, your genes instruct your cells to split into two by making a copy of your chromosomes. • Meiosis: The process of making egg and sperm cells for the next generation. During meiosis, chromosomes copy themselves with half the amount of chromosomes as the original (from 46 to 23). That’s how you’re able to get your genetic material equally from each parent. How do genetic mutations happen? Genetic mutations occur during cell division. When your cells divide, they hand-write your body’s instruction manual by copying the original document word for word. There’s a lot of room for error during cell division because your cells might sub...
