DNA is relatively new to the crime scene. Forensic investigators started using DNA in the 1990’s when it became highly reliable in proving criminal activity in people.
DNA is gathered at crime scenes and it allows police to pin point who exactly was at the crime scene. From there, they can conclude who and how the crime was committed. Examples include matching DNA at crime scenes, recognizing familial relationships and paternity testing.
DNA has proven to be a highly valuable tool and will continue to help forensic science.
For many of us out there, you may never have to encounter genetic testing. There are few, however, who would benefit from genetic testing. What is genetic testing and do you need to get one? (Continued)
Here is a great instructional video on how to do a DNA paternity test. It’s quite simple and very effective. Just follow these simple tests and any court will deem your test valid.
What happens when you submit your DNA sample in the mail? You submit a a mouth swab and it is sent to a laboratory and scientists there use tests to decipher your DNA.
For most DNA tests such as a paternity test or sibling test, the procedure is the same. They perform a polymerase chain reaction in order to get a DNA profile. A DNA profile is a a small snapshot of the DNA and scientists use this profile to run statistical tests and compare two profiles to see if they are related. If two profiles are related they show similar patterns.
