DNA is used in a variety of ways, from forensic science to understanding our ancestry.
Forensic Applications of DNA
One of the most significant applications of DNA is in forensic science. DNA analysis can play a crucial role in the justice system.
- Convicting the Guilty: DNA evidence from a crime scene can be compared to a suspect's DNA profile. A match can provide strong evidence of guilt. According to the provided text, DNA profiles can be compared against other profiles within a database.
- Exonerating the Innocent: Conversely, DNA evidence can also clear wrongly accused individuals. If a suspect's DNA does not match the DNA found at the crime scene, it can prove their innocence. The reference states that DNA can be used to clear an innocent person.
- Sources of DNA Samples: Samples for DNA analysis are typically obtained from blood, hair, or body fluids.
