DNA and Biological Evidence
Forensic scientists analyze biological evidence to help solve a variety of crimes. These analyses can show that biological materials from a specific individual were found at a crime scene, can help inform how a victim may have died, and can even bring identity to unknown human remains found in advanced stages of decomposition. Forensic biology is used to determine what types of biological stains, such as blood or semen, are left at a crime scene and to link those stains to individuals through DNA analysis.
