There way that I think is really interesting

 

            There are
many ways that genetic analysis and new technologies have helped our world. One
way that I think is really interesting is genetic analysis in microbial forensic
studies. With a decently low cost of preparing biochemical weapons, the
technology field of microbial genetics has become an important field (Budowle,
2005). In this essay, I will discuss how technologies in genetics help to
analyze and interpret threats from bioterrorism acts and other examples of how
genetic techniques have helped in the field of forensics.

            The decently low costs of preparing
or taking apart bioweapons, we have begun to have a greater need to be able to
interpret microbial evidence from the types of terrorism or crime. A major way
that scientists have done this is by the analysis of nucleic acids. A few types
of the genetic markers used for microbial forensics are single nucleotide
polymorphisms, repetitive sequences, insertions and deletions, or mobile
elements. The technologies can consist of PCR of genomic sequencing. The end
goals of these methods is to be able to figure out who was involved in these
type of events in order to prosecute them or be able to take actions for policy
decisions involved in the different nations. When these type of attacks happen,
the first step is to figure out what the toxin was so they can find the
appropriate cure or treatment if one exists. This helps the microbial lab to
try and link the toxin with who the perpetrator may be. They then take the
weapons or anything involved in the attack and check for evidence such as hair,
fingerprints, or human DNA. Techniques such as culturing can play an important
role in this assessment. This is not a good technique though because it can be
very slow. Nucleic acid analyses are being more popular for clinical diagnosis
(Budowle, 2005).

            Another
interesting article I found talks about how nonhuman DNA is becoming another
way to prosecute individuals for crimes committed. Criminal courts have not
often dealt with animal DNA evidence in many crimes so it is up to genetics
labs to make sure the DNA is admissible. Validation of accuracy, good sampling,
and evidence handling are all important in getting the criminal to accept this
evidence in the prosecution of individuals when animal evidence could help to
put them away. The first case where animal DNA was tested was in 1995 when a
jacket found on the scene of a crime linked the murderer to the crime because
his cat’s hair was found on the jacket. There was no human hair on the jacket,
so the cat’s hair is what secured the murderer’s fate of being guilty in the
criminal case. After studies showed that animal and human genome can be
compared to each other, it was much easier to show the courts that nonhuman
evidence could be just as important as human evidence (Cassidy, 2005).

            I have
always found genetic testing very interesting. The fact that it can be so
important in forensics was really interesting to me. Advances in genetic
testing techniques are constantly improving our world. Terrorism has become a
large threat in our world and the ability to figure out the weapons used and
try and link it to the guilty is a really important advancement. I also agree
that any evidence in a criminal case should be used in court even if it is
nonhuman DNA. Genetic testing techniques will continue to grow and improve our
world.
