Single Nucleotide Polymorphisms

Nowadays, DNA is a crucial component of a crime scene investigation, used to both to identify perpetrators from crime scenes and to determine a suspect’s guilt or innocence (Butler, 2005). The method of constructing a distinctive “fingerprint” from an individual’s DNA was first described by Alec Jeffreys in 1985. He discovered regions of repetitions of nucleotides inherent in DNA strands that differed from person to person (now known as variable number of tandem repeats, or VNTRs), and developed a technique to adjust the length variation into a definitive identity marker (Butler, 2005). Since then, DNA fingerprinting has been refined to be an indispensible source of evidence, expanded into multiple methods befitting different types of DNA

The medical advances being made feasible by genetic testing are very exciting. It is possible for people with predispositions for genetic defects to know in advance if they will have a healthy child or not. If they find out there is a problem they can choose to terminate the pregnancy or they can prepare in advance for their child's special needs. There is even new technology called Ex Utero genetic testing. This test is performed on eggs fertilized through in vitro fertilization before they are even put in the mother's uterus. Understanding genes in the developing human will help doctors understand the nature of genetic diseases and may lead to countless other medical breakthroughs. Though it is probably a long way off doctors may one day be able to manipulate genes. If this is possible some genetic problems may be cured.

Technology is developing every day. The automobile was revolutionary, and then they introduced the plane. Cell phones can connect us with people around the world. Self-driving cars are in development today! Revolutionary inventions are the expectation nowadays, but a new discovery is sparking controversial questions in the science world. Is it acceptable to alter a baby’s genes to make it a better human? Genes are the instruction book of the body, and they determine everyone’s attributes and how people act in their environment (Medical News Today). Some people say that everyone is different for a reason, and others think customizing the genes of children was meant to happen. Altering an infant’s genes is acceptable to prevent hereditary diseases, but the line should be drawn at making an artificially smarter, stronger, or prettier human.

Other than our desire for perfection, we as humans also have another desire: to learn about ourselves. We have the desire to explore our humanity. We often like to look within ourselves and question things about ourselves. In this way, eugenics should be explored in order to answer questions we have about ourselves. " Humanly speaking, the new genetics seems to have five dimensions or meanings: (1) genetics as a route to self-understanding, a way of knowing ourselves; (2) genetics as a route to new medical therapies, a way of curing ourselves; (3) genetics as a potential tool for human re-engineering, a prospect I find far-fetched; (4) genetics as a means of knowing something about our biological destiny, about our health and sickness in the future; and (5) genetics as a tool for screening the traits of the next generation, for choosing some lives and rejecting others."

DNA profiling involves testing mini-satellites one at a time which then goes on to produce an image which is much simpler than genetic fingerprinting. It provides a pattern which is unique to a particular person and is therefore suitable for forensic purposes. (Turnpenny, P et al 2005).

DNA is one of the most important pieces of evidence that a criminal justice agent can use in a court of law. There ae slim to no crimes committed that doesn’t have some type of DNA evidence left behind. Some DNA evidence could be, but not limited to, fingerprints, blood, hair, and any other bodily fluids. DNA is known as Deoxyribonucleic Acid, and is one of two types of molecules that encode genetic information (Medicine.net, 2017). DNA is characteristically unique to each person individually, unless they are a twin. DNA dictates a person’s look such as their eye color, blood type, height, hair color, skin color, etc. With this genetic information, intense testing can be done to find who may be connected to the genetic makeup of each stand

In the essay, “DNA fingerprinting: Cracking Our Genetic ‘Barcode’,” by Elaine Marieb, illustrates how significant DNA fingerprinting is today. She initiates a candid example of how New York City’s World Trade Center massacre killed more than 3, 000, left millions of bodies distorted, charred, and decayed. It was the staple for the ever-increasing need for DNA fingerprinting.

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

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.

You may have not thought about issues that come along with genetics and the genetic makeup of a human being. This includes but not limited to how your child will look, will the offspring have your features, the fathers features, or even one of the grandparents' features. This has caused many stakeholders to debate on whether genetic engineering should be allowed and to what extent. Meaning, should we be able to design our children based on how we want them to look or to prevent them from obtaining some detrimental conditions? Most would base their opinions on the “fun” part of designing your baby and how cool that may seem. In a study by Salah, Yaz, a publisher for Emaze

I have seen how DNA and genes passed down from our parents can control our internal body and our outward appearance, like our physical and emotional health, intelligence, eye color and skin color. DNA is used to determine that kind of stuff. In some of our society, what genetic disease you have can have impact on what you can do. For example, if you were to have hemophilia, it may limit you on playing sports because if you get cut, you can bleed for a long time which would be very dangerous. Physical features can also have an impact on your role in society. If you are considered strong or handsome/beautiful you might be more successful at school and in your job career. After watching the movie Gattaca I think it would be neat to genetically

The possibility of predicting not only diseases, but specific traits such as eye color, height, and intelligence levels makes eugenics very possible and much easier to attain. Not only is eugenics ethically incorrect, but it will also have a negative effect on our genetic diversity.

Science is now able to better improve human health and safety thanks to the advanced modern technology and medicine that are available. Yet with today's technology being implemented into science comes the questions of human morality, or bioethics. One of the bioethics debates is on the coined term “Designer babies”; on if or where society should draw the line on genetically altering our children before they are born. With the technology able to stop hereditary diseases, the scientific development’s are able to change the child’s “eye color, hair color, social intelligence, right down to whether or not your child would have a widow’s peak” before the child is born. From the options on choosing whether or not your child will look or act a certain

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.

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
