Argumentative Essay On Dna Testing

Is DNA testing worth all the money and effort we put into it? Sometimes it is not and this is why. Analyst Kathryn Troyer did some tests on Arizona's DNA database. She stumbled across two different felons with incredibly similar DNA profiles. Both men DNA surprisingly matched at nine of the thirteen loci. The FBI approximated that the odds of unrelated people sharing those genetic markers are about 1 in 113 billion. The two men were in no way related, they were not even of the same race. The FBI desperately tried to hide this.

First, according to the Innocence Project, by 2016, roughly 337 people from the U.S. had been absolved after being convicted solely based on DNA evidence, including some individuals who were even on death row. Homogeneous DNA profiles between two or even more people, even some individuals who are non-related, have many scientists and legal specialist doubting how accurate some of the FBI statistics really are. A

It stores DNA identification records of many people convicted of crimes. Secondly, it also contains analyses retrieved from unknown human remains. Finally, it kept analyses of genetic samples retrieved from a crime scene.

Deterioration breaks DNA up into pieces too tiny to possibly work with, fundamentally destroying the evidence entirely. Extreme caution must be taken to assure the chain of custody is secure during every process, from the crime scene to the lab. Along with being prone to deterioration, DNA can also be easily contaminated with immaterial DNA from either the somewhere at the crime scene or by someone's skin accidentally touching the DNA sample without taking the right precautions.

Is DNA testing really worth the money and effort everyone puts into it? Sometimes it's hard to tell. Many times it seems like everything's going fine, then people look further into it to see it’s not going as well as everybody
