“We all have dreams. But in order to make dreams come into reality, it takes a lot of determination, dedication, self-discipline, and effort. Our world wouldn’t be as advanced as it is today without science. In my paper I’m going to be talking about DNA fingerprinting and RFLP analysis. These all use genetics in some way and have a very big impact of our modern world. I’m going to be talking about the history of these two topics, the science behind the technologies, what the technique is used for and the controversy surrounding the topic.
In 1984, DNA techniques were first developed by Alec Jeffery’s. Alec Jeffery’s is one of the greatest contributors to modern genetics, he received an education at the university of oxford, and the two years at oxford he transferred to the University of Leicester where he became a professor. Today he is a professor in the genetics department. After years of studies and the combination of his recently acquired molecular biology experience with his interests in human genetics on September 10th, 1984 his team got there first truly awful DNA fingerprint. However he then realized that he had a DNA- based method for biological …show more content…

There are several different ways our society uses DNA fingerprinting. Fingerprinting is used for personal identification, paternity and maternity, diagnosis and cures for inherited diseases. You might ask how DNA fingerprinting can be used for diagnosis and cures for inherited diseases, well your family might have a long history of having a specific disease for example cancer. DNA fingerprinting catches these because your DNA can tell us ahead of time if you are vulnerable to the disease or not. A show called the Maury show uses DNA profiling to figure out if the child is really the parent’s child. Once again there are multiple uses for DNA profiling, it helps people every

The Department of Justice says, "States began passing laws requiring offenders convicted of certain offenses to provide DNA samples. " That DNA evidence can help convict someone of a crime and it helps to uncover more things about the crime itself. Investigators have been using forensic science to help them solve cases since before the 90 's, mostly fingerprints that were found at the crime scenes and on the victims (O 'Brien). DNA evidence has solved countless cases including ones that happened over a prolonged period of time because of the technological advancements there is

It is a great technological innovation that can help bring evidences and fact faster. In the article The DNA Wars Are Over, “Forensic use of DNA technology in criminal cases began in 1986… In one of the first uses of DNA in a criminal case in the United States, in November 1987.” Sadly in 1985, DNA testing was not popular in the U.S. investigation and was not available in Cole’s case. I believe the U.S. court system is improving and yes there are a lot mistrials and wrongful conviction cases, but you cannot avoid the fact that DNA testing can bring better truth than just relying on statements of both

DNA testing has been changing lives for the wrongfully convicted. Innocent people are being released from prisons because of DNA. Ronald Cotton was fortunate to have been found innocent thanks to DNA evidence after being imprisoned for years. It may not always be that way, though, there are still people being locked up once DNA has ruled them out.

Do you believe that we should change human DNA and genes to make “better” people? I think that the answer really depends on what you are changing or trying to make better about a person. If the person has a genetic deformity, then the answer would be yes. You should try to help that person to be “better”. If we are talking about a person who is normal, that wants to be better at a sport or a talent then the answer would be no.

DNA profiling was first established in 1985, and has seen extensive use in the field of forensic science and genomics. DNA profiling was developed in 1984 by Alec Jeffreys, after he noticed that certain sequences of highly variable DNA, which were non-coding, were repeated within genes (McKie, 2009). He recognised that each individual has a unique pattern of non-coding DNA sequences therefore allowing them to be profiled. The process has helped the police in solving crime cases over the years, as every individual’s DNA is unique to their characteristics, forensic scientists can use the DNA at a crime scene to identify the victims, reduce the number of wrongful arrests, increase the reliability of evidence, and provide information at crime scenes where there are no witnesses. The purpose of the investigation is to analyse whether newborn infants should have their DNA profiled and stored in a database at birth.

Fingerprinting is method based on the uniqueness of the skin pattern - that is, each person has a completely individual pattern of papillary lines. These patterns do not change throughout life and have the property of recovering from damage to the skin in its previous form. On the one hand, this method almost completely eliminates the mistake, and on the other hand it is very cheap and easy to use (in contrast the method of identification of a person by DNA). Fingerprinting allows: 1) to identify the person who left the prints, according to the general and particular features of the papillary pattern displayed on them; 2) to exclude individual from among those who have touched the object; 3) to narrow the group of individuals suspected of the particular crime (for instance, provided that the imprint shows traces of a scar, a burn, a wart or some other distinctive feature).

In the lab report three students are tested along with one suspect. Student number two’s DNA matched the suspects DNA. The student’s DNA’s are cut with five different enzymes as well as the suspects DNA. Student two’s DNA matched exactly with the suspects DNA; the other two student’s DNA did not resemble the suspects DNA at all. (Choi, et al, 2008) DNA fingerprinting is used a lot in determining who committed a crime.

In King, Justice Kennedy referred to the invention of DNA technology as “one of the most significant scientific advancements of our era.” This statement has been criticized, but the impact of DNA technology has been significant. Currently, forensic analysts can use “junk” DNA to identify a person with near certainty. Law enforcement can collect a person’s DNA through saliva. The sample is then uploaded to CODIS, a national network of DNA databases.

As we gone further along in history we can now detect DNA, DNA from dental, saliva, cameras, and facial sketches. “DNA databases have been raised using arguments from biomedical ethics; these databases are used in a complete Different context from other biomedical tools. Because they are used in the struggle against crime, the decision to create or store cannot be left by the individual. Genetic profile Instead, this decision is made by officials of society.” Annemie Patyn and Kris Dierickx Shows the pivotal role evidence has on solving crimes.

A DNA databank is a database of DNA profiles on everyday people. It can be used for a lot of different things such as: analysis of genetic diseases, genetic fingerprinting, or genetic genealogy. DNA can also be used to solve crimes by matching samples from convicted felons to unsolved crimes DNA database for the most part is mainly private. The United States has DNA of most everyone in the United States of America. DNA technology has proved to be a valuable investigative tool that has helped to exonerate the innocent and to bring those responsible for serious crime.

In today's’ world, privacy is becoming a bigger concern but is growing increasingly more non-existent. We store fingerprints on our phones, our and our passwords online, and many other things that used to be kept very private and personal. There are hundreds of to get DNA from someone that are non-intrusive, like getting their fingerprint from a phone or getting saliva from food or drink they had. The 4th amendment protects citizens from unlawful and warrantless searches, but with the amount of DNA that one leaves behind everywhere they go, your DNA is not really considered private anymore. Another reason why is because, in the majority opinion, Justice Kennedy writes that, “the use of DNA for identification is no different than matching an arrestee’s face to a wanted poster of a previously unidentified suspect.”
