All it would take is one sneeze. Your DNA would be all over this book. That's right. Your spit has DNA in it. So does your skin. And your blood.
That's important to police because everyone's DNA is different. With the right equipment, detectives can match a person with some blood left at a crime scene. They've put murderers in jail that way. They've also freed innocent people.
Want to know more? Get some evidence about the following:
- how almost everything about you is in your DNA;
- how investigators identified some criminals by the DNA they drooled on their hamburgers;
- how a cat's DNA sent a man to prison for murder;
- and whether you might have the right stuff to become a DNA specialist.
Warning: In this book, investigators look for DNA in some disgusting places. They can find it in bloodstains. They get it from chewed-up food and pulled-out hair. There is also plenty of DNA in dead bodies. So...read at your own risk.
