What part will DNA play in the Boston Marathon bombing investigation?

Female DNA was found on a piece of at least one of the explosive devices used in April 15's Boston Marathon bombing. However, police have not yet determined whether or not the DNA discovery indicates a woman's involvement in the attack.

What is DNA? DNA, or deoxyribonucleic acid, is a molecule that carries a set of instructions. These instructions tell our cells what to do, which determines physical traits such as eye color or height. The information encoded on the DNA molecule is what makes a person unique.
