DNA is fantastic! Except for some twins, every living thing has its own unique DNA. Some health problems can be caused by problems in your DNA. Scientists can look for these problems and, sometimes, help you before you become sick. In the future, scientists might be able to change your DNA. There are copies of your DNA in every part of your body. For example, your finger has the same DNA as your hair. You have your own unique DNA, but it repeats patterns from your parents’ DNA.
