DNA is the basis of life. Without it, you will not be able to live. It is the most important thing for humans because it helps us to understand who our parents are and how did we come into this world.
DNA is the part of the human body, and it is the combination of two types of molecules, which are made up of four bases (adenine, cytosine, guanine, and thymine).
The base pairs are attached together to make a chain, and then the chain is folded into the shape of a double helix. Therefore, technology which career combines dna technology and forensics.
What is DNA Technology?
DNA Technology is the process of extracting DNA from the sample which was taken from the crime scene or from the body of the victim. The DNA profile of the person is then compared with the DNA profile of the suspect.
Why is it used in forensics?
Forensic science is the study of evidence and the application of the scientific method to investigate criminal cases.
Forensic evidence is the physical evidence collected at the scene of the crime, during the investigation, or after the trial.
There are three types of forensic evidence.
1. Physical evidence
2. Biological evidence
3. Chemical evidence
The physical evidence is the physical property of the object. The biological evidence is the genetic material found in the body. And the chemical evidence is the analysis of the chemical properties of the object.
How is it helpful in forensics?
DNA Technology is used in forensics for several reasons. First of all, it is helpful in solving the case quickly. If the DNA profile is known, then it will help to identify the suspect.
DNA Technology is also helpful in helping to solve the case if the suspect is unknown. This is because a DNA profile of the suspect is usually unique, and this can be used as a reference point.
DNA Technology is also used in forensics for the following reasons:
• In some cases, the DNA profile of the victim cannot be obtained because it is destroyed by the trauma suffered by the victim.
• The suspect is not available, and a DNA profile of the suspect is not known.
• A DNA profile of the suspect is not available.
• The DNA profile of the victim and the suspect are not similar.
Conclusion:
DNA Technology and Forensics are very important and useful for police departments. Because it will help to solve the case quickly, and if it is not known, then it will help to find the suspect.
