If DNA is presented as convincing evidence, then I believe the jury should be informed of the possible risk factors associated with genetic analysis. The increasing popularity of forensics in media Dna profiling essay as TV shows, which often represent DNA profiling and forensic in an oversimplified manner, has given the Dna profiling essay a skewed view of real life forensics.
As with any relatively new technology, there are certainly going to be issues and roadblocks. This is not to say that at its current stage forensic DNA should be taken lightly. Moreover, in some cases where the victims are hard to identify, DNA analysis can give these victims an identity Thelin.
If other evidence in the case raises doubts or if the collection and analysis was not error-free, then it should not be taken as definite. Contamination of samples, which may turn a positive identification into a negative one, is a key problem area in the processing of DNA samples.
These techniques above indeed offer unique supplemental evidence, but I believe more time and work is needed in order to make DNA forensics more invaluable in the Dna profiling essay. Currently, DNA analysis is not completely automated, and human errors can play a huge factor in the validity of DNA evidence.
This includes expanding current national databases and improving upon existing technology and techniques. DNA In trials where a defendant may be given a life or death sentence, is it reasonable to place so much faith in genetic forensic results?
There needs to be consideration for the matching of family members such as distant relatives or twins. Furthermore, there have also been cases of planted fake DNA evidence, and the improper or incomplete collection of DNA may also question the validity of the evidence and raise privacy concerns Pollack.
However, with lives and innocence at stake, everything, including genetic analysis, should be carefully reviewed and tested thoroughly. Due to its accuracy, DNA profiling in forensics not only has the power to positively identify criminals, but also make sure an innocent person is not wrongly convicted.
One of the main techniques used nowadays is the combination of PCR and short tandem repeats. DNA analysis has become the most advanced method of identification, replacing fingerprints. Forensic DNA analysis does not only play a role in matching a certain individual to a crime, but also can be used to prove innocence also.
As a result, though the chance of having a match with a relative or twin may be very small, the risk of human error in laboratories is significantly larger. For example, in January ofa perfect DNA match at 13 regions was discovered in only 30, samples Felch. As the progress of science and technology continues to reach new heights, there is no doubt that new and more efficient techniques will be developed that may address many of the concerns that current forensic DNA profiling poses today.
A convincing case should be made through a combination of evidence, rather than just relying on DNA itself. By amplifying specific polymorphic regions of DNA, unique number of repeats at specific locations can be assigned to individuals Human Genome Project.
In the early stages of DNA forensics, restriction fragment length polymorphisms RFLP were used by digesting DNA with restriction enzymes and then analyzing the resulting fragment lengths which were unique to individuals Davidson.
I believe that although genetic evidence can often make a great case, it should always be viewed with skepticism.
DNA gathering is less invasive than a blood test, as a simple cheek swab can be sufficient for analysis. However, forensic DNA profiling is here to stay, and as more work and effort is placed into its research and development, justice will be served to the guilty, keeping criminals in jail and the innocent free.
Due to its accessible and hardy nature, samples of DNA are sometimes the only evidence that is available for collection, and combined with its accuracy, make it a very valuable asset in the courtroom. So how is it possible that DNA is used as evidence in the courtroom?The Dna profiling is one of the most popular assignments among students' documents.
