Forensics and DNA Fingerprinting

Solving Mysteries with DNA

DNA fingerprinting is a technique used to identify individuals by their unique DNA patterns.

How Does it Work?

  • Scientists compare sections of DNA that vary between people.
  • This creates a pattern—like a barcode—that is unique to each person (except identical twins!).

Uses in Real Life

  • Crime scene investigations.
  • Paternity and family testing.
  • Identifying disaster victims.

Why is it Important?

DNA fingerprinting has revolutionized law enforcement, making it possible to solve crimes and reunite families.

Examples

  • Police match DNA from a crime scene to a suspect.

  • Families separated by disasters are reunited using DNA analysis.
