In his New York Times article “Building a Face, and a Case, on DNA” Andrew Pollack discusses recent advances in technology, and science, both connecting to DNA. Pollack explains DNA phenotyping, the process of predicting an organism's phenotype using only genetic information collected from genotyping or DNA sequencing, and how police and other law enforcement have been applying it to solve crimes. By using DNA phenotyping law enforcement can generate a face by a computer using only DNA found at the scene of a crime. Although DNA phenotyping can determined a suspect’s eye and hair color accurately, it still has a ways to go to being able to fully generate a suspects face.
DNA fingerprinting is a scientific technology involving the extraction, replication and arrangement of strands of an organism’s DNA. This results in the formation of a genetically distinctive fingerprint that is unique to the organism which the DNA sample was originally extracted from. Because of the specificity of a DNA fingerprint, the application of this technology can have a substantial influence on many aspects of society. Accessibility to a DNA database allows for higher efficiency in forensic investigations, personal identification, maternal and paternal testing. The availability of a national database to police officers and forensic scientists would equate to increased productivity in investigations and prosecution of suspects in a
DNA testing is a critical and accurate tool in linking accused and even convicted criminals for crimes, and should be widely used to assess guilt or innocence before jail sentences are imposed. It was started up by scientists Francis C. Crick and James D, Watson in 1953 as they had described the uses, structures and purpose of the DNA “deoxyribonucleic acid” genetic fingerprint that contains organism information about an individual (testing
When analyzing DNA, the analysts create a DNA profile for each evidentiary piece of DNA. The DNA profile is based on 13 markers, or locations, within the genome. These 13 markers are chosen because they show a high variability between individuals. By using these 13 markers, the probability of 2 individuals having the exact same 13 markers is infinitesimal. But DNA profiles as they are now are made for identification purposes only. The profiles are not meant to contain personal genetic information (Matheson, 2016). But through the work of Susan Walsh, together with colleagues in the Netherlands, they have been able to create models for eye colour and hair colour. For the model on eye colour, they have a 95% accurate predictability rate, but only for brown and blue eyes. They have not done as extensive of work on the other colours of eyes. For the model on hair colour, they have a 90%
Bodily privacy is a significant issue in Genetic Profiling, as it is a human right which is in constant need of law reform. Technology is continually advancing, and genetic
Beginning in the mid-1980s, the development of DNA analysis technology has revolutionised the field of forensic science within the criminal justice system. As the refinement of procedures and technology continues, even minute samples of biological material (including blood, saliva, semen and skin cells) are able to be analysed and used to link or acquit perpetrators of crimes. (Whitney, R n.d.)
Perhaps the most critical improvement in criminal examination since the happening to one of a kind finger impression ID is the usage of DNA development to convict punks or get rid of persons as suspects. DNA examinations on spit, skin tissue, blood, hair, and semen can now be reliably used to association guilty parties to wrongdoings. Dynamically recognized in the midst of the past 10 years, DNA development is in the blink of an eye by and large used by police, prosecutors, shield course, and courts in the United
Currently, the DNA examined and recorded for forensic purposes does no reveal the most personal of these details but the technology for doing this exists or is likely to exist in the future. The ability to use DNA to make family connection is currently the main issue raised by the use of DNA technology in law enforcement, which is bound to result in futuristic invasion of privacy or possible harassment of those who happen to be family members of possible
Parents today enroll their children in the best possible schools and will do anything to make sure their children look up to standards. Possibly in a few decades parents would be able to choose from a plethora of traits: hair color, eye color, bigger muscles and so on that their children could obtain. Maybe they'd like to add a few inches to a child's height. Or improve their kid's chances at longevity by tweaking inherited DNA. Planning the child’s genetic future could really give him/her a head start in life.
Every day DNA technology becomes more advanced and innovative, for example can match the smallest amounts of biological evidence to a criminal offender. Future DNA techniques will be applied to existing systems and testing methods that will become more automated and will be more effective and less time consuming. Instead of waiting months of DNA results the future will provide instantaneous means for DNA profile development.
DNA forensics can also narrow down suspect pools, exonerate innocent suspects, and link crimes together if the same DNA is found at both scenes. However, without existing suspects, a DNA profile cannot direct an investigation because current knowledge of genotype-phenotype relation is too vague for DNA phenotyping. For example, a profile from a first time offender that has no match in any database may give the information that the criminal is a left handed male of medium stature with red hair and freckles. It would be impossible to interview every man who fits that description. However, with available suspects, DNA forensics has many advantages over other forms of evidence. One is the longevity of DNA. Although it will deteriorate if exposed to sunlight, it can remain intact for centuries under proper conditions (Sachs, 2004). Because DNA is so durable, investigators can reopen old cases to reexamine evidence.
Most parents would do almost anything for their children to be the best and know that in life they will be successful and ahead of the game, but what if even before they are even born you could alter their genes to give them an even greater advantage. This would allow one to “create” a child who is smarter, taller, and prettier, even if the parents never carried any of these traits. As the human race continues to develop and modern technology continues to advance, we have been able to create new inventions that could potentially help us overcome daily issues linked with diseases and mutations, but although to some this seems like an incredible idea, the motion of one day being able to modify your unborn baby to look and be who you want is not only morally wrong, but could result in drastic environmental changes. Genetically engineering has influenced many debates as to whether the ethics behind the motion are right, and like most scientific discoveries comes with many advantages and disadvantages.
