How Can DNA Technology Be Used In Forensics?

DNA technology is used in the field of forensics for solving criminal cases. The use of this technology is constructive for police as well as investigators because it can be used in identifying criminals as well as suspects. The science behind this technology is DNA testing but which is a negative consequence of using DNA technology in forensics? And the way this test is conducted is explained in the article.

The science behind DNA testing is that it helps us to identify the identity of an individual. DNA testing is a type of biotechnology that can be done through two different methods, i.e., direct and indirect.

Direct method:

In the direct method, DNA samples are obtained from various sources such as hair, blood, semen, bone, skin, etc. The sample is then analyzed to identify the unique genetic code.

Indirect method:

The indirect method is conducted based on the forensic clues at the crime scene. The evidence is collected from various sources like blood, hair, skin, and nails. The analysis of these clues will lead to the identification of the suspect.

Why is DNA testing necessary for forensics?

DNA testing is one of the most beneficial tools for criminal investigation. This technology makes it possible to identify the suspect or the victim from the crime scene. The crime scene is the place where the murder took place. During this analysis, we will find several forensic clues which can lead us to the culprit.

The crime scene is the place where the murder took place.

What are the benefits of using DNA testing in forensics?

Benefits of using this technology include:

  • DNA testing can detect the presence of a specific DNA fragment on a crime scene.
  • It is possible to identify the offender or the victim through the crime scene analysis.
  • It can reveal the relationship between the suspect and the victim.
  • It is also possible to find the location of the crime scene.
  • DNA testing can also confirm the crime’s date.
  • It is also able to determine the gender of the suspect.
  • It is also possible to determine the age of the victim.
  • Identifying the weapon used for the crime is also possible.


DNA testing is being used in the field of forensics to solve crimes. It is a valuable tool that can be used to find the identity of a person.
