At a point in time, forensic science was a foreign word that only a few understood. Even fewer were part of the industry. However, today’s world is filled with murder mysteries – from TV series to best-selling authors, forensic DNA testing has become a household term. But beyond the show you watch or the book you read, how much do you really understand about the science and how it works?
Here, the experts from Validity Genetics provide you with a glimpse behind the scenes of forensic science.
What is forensic science?
“The forensic science behind Infidelity DNA Testing is a critical element of Infidelity Testing. Forensic scientists examine and analyze evidence from samples to develop objective findings that can assist in the investigation of infidelity to absolve or confirm suspicions.
Common forensic science laboratory disciplines include forensic molecular biology (DNA), forensic chemistry, trace evidence examination, and so on.”¹
How does forensic DNA testing work?
Now that you have an understanding of what forensic science is, let us take a look at how it works. First, it is imperative to realize that everyone’s chromosomes contain markers in the DNA sequence. These chromosomes repeat multiple times. The number of times they repeat at each of the markers varies from person to person. Furthermore, each person has two copies of each marker. One is inherited from their mother and another from their father.
Forensic scientists use these markers to determine the DNA differences between two sets of evidence. Similarly, laboratories use this same procedure to determine other tests, such as a paternity test.
