From the Paper
"Genetics today is on the cutting edge of biological science, and scientists working in this area are involved in a wide variety of pursuits that will have profound implications for our future on this planet, with projects including the creation of new biologic entities, curing diseases, manufacturing synthetic versions of biologic substances, identifying different genetic codes and what they do, and perhaps finding a way to control that genetic information to produce animals with certain characteristics or without certain characteristics, including greater strength, resistance to disease, and a higher yield in meat, eggs, dairy products, or whatever they provide. Geneticists have already accomplished many of these things with grains, plants, and even certain farm animals. They are addressing disease through the creation of new strains of bacteria by means of recombinant DNA ..."

Abstract
This paper explains that, for many centuries, farmers fought pests using everything from usual plant-breeding techniques to chemicals, such as pesticides and herbicides; but, as new chemical treatments increased health and environmental concerns, gene modification became the agro-scientists' tool for advancing molecular biology. The author points out that over 40 plant varieties have completed all of the federal requirements for commercialization as per the FDA and the United States Department of Agriculture (USDA). The paper explains that, although customers in the U. S. are accepting GM foods, customers in Japan are beginning to show a strong liking for unmodified fruits and vegetables in supermarkets offering both GM foods and unmodified foods.

From the Paper
"Genetically modified foods (GM foods or GMF) provide opportunities to swiftly enhance crop nature such as yield, pest resistance, or herbicide tolerance, which is not successful with conventional methods. From the predecessor to plastics to consumable vaccines, GM crops can be molded to make completely artificial substances. The methods of modern genetics have made it probable for the direct action of the genetic makeup of organisms. Using genetic engineering, plants from wild relatives, other distantly related plants, or almost any other organism can be relocated with simple genetic qualities into the crop."

Problems With DNA
From the Paper
"The forensic use of DNA has become widely accepted in America today as providing error-proof evidence for criminal cases. Many convictions are made on the strength of DNA evidence alone, and some fewer number of accused "criminals" have been cleared of all charges on the account of late-discovered DNA evidence. Depending entirely on one's perspective, DNA sequencing may be either a godsend or one of the most serious threats to an objective justice system to have surfaced in a hundred years. On the one hand, DNA evidence can accurately link a suspect to physical evidence left at the murder scene with a striking accuracy, with the probability for error being only one in five million when considered a (genetically) average suspect and an average gene pool."

Abstract
The paper explains that a DNA profile refers to unique identifying characteristics of an individual. The paper relates that DNA profiling and the collation of databases that can be shared allow for a successful and effective way of combating crime. The paper offers a variety of other reasons why DNA profiling and the maintenance of DNA databases can be useful. The paper discusses how this technology is being constantly improved and there are indications that fast and more effective methods of profiling are being developed.
From the Paper
"The science of DNA profiling has many applications. The most common usage of this technology is to rapidly identify the criminal perpetrator in a crime. An article from the University of Utah states: "DNA profiling has helped to acquit or convict suspects in many of the most violent crimes, including rape and murder." (Can DNA Demand a Verdict?) DNA profiling can be equally effective in preventing an innocent person for being wrongly convicted of crimes."

Abstract
This paper explains that DNA evidence exists in biological materials, such as blood, semen and even perspiration and can be found on a variety of items from cigarette butts to eyeglasses, even decades old evidence can contain DNA. The author points out that one of the biggest disadvantages of DNA testing is, if it is not performed correctly, the results are worthless. The paper relates that in the field, DNA fingerprinting is one of the investigator's forensic tools but its use requires full training in the process for collecting DNA evidence.

What I Would do as an Investigator in this Field and Why I Would Choose DNA Fingerprinting
From the Paper
"Lastly, Smialek, Word, and Westveer note a primary disadvantage of DNA fingerprinting is the ease in which it's contaminated. Samples have to be collected and handled with gloves that have to be changed often. Disposable instruments, or those that are thoroughly cleansed can only be used. Even talking, sneezing or coughing over evidence can make it worthless. In addition, there is the backlog of DNA samples to be processed which lead to lengthy waits between collecting and interpretation."

From the Paper
"DNA is organized as two complementary strands that are linked together with bonds that can be separated. Each strand of DNA is a chemically linked chain of nucleotides, which are made up of a sugar, a phosphate and one of four kinds of nucleobases, often simply referred to as bases. These bases are: adenine, thymine, guanine, and cytosine, abbreviated as A, T, C, and G. Furthermore, these bases only pair up properly with one other base, A with T, C with G, and vice versa, on their complementary strand ("DNA")."

Conclusion
From the Paper
"The internet has made so many sites and processes available to the average person that home DNA testing may actually be a reality in the near future. But, this plethora of information is actually a bit overwhelming and therefore confusing. Results obtained on one site may not necessarily agree with the results of another site which obviously leads amateur Genomics practitioners such as my self to begin to doubt returned results and thus require professional confirmation. The key is that DNA Sequencing and interpretation will alter mankind's ability to identify 'medicine less' cures and maybe even lead to the creation of completely altered super humans. "Initiation of DNA replication holds the clue to what controls cell division and hence growth and differentiation." (Adams, 1991) "

Next, the paper gives examples of good DNA and bad DNA and explains each form of DNA testing, how it is done, why it is done, and the results. Additionally, the paper explains DNA fingerprinting.
From the Paper
"Every human body is made up of deoxyribonucleic acid, also known as DNA. DNA the responsibility of DNA is to preserve, copy, and send out information within the cells from generation to generation. (Mitochondrial DNA and Human Evolution) In humans, DNA molecules are made up of two strands that wrap and twist around each other. (Darwin to DNA, Molecules to Humanity) They look like a twisted ladder. When it looks like this, it is referred to as a double helix. DNA is enclosed in chromosomes. Chromosomes are the cells within the DNA that carry the gene information. (Inheritance of Mental Illness) (Genes and the Mind) They are located in the nucleus of every cell."

This research paper explains what DNA is and how it is used to solve criminal cases. Additionally, it discusses the implications of DNA fingerprinting in solving cold cases, with a focus on collection methods and applications in the state of California. The research analyzes and discusses the feasibility of DNA testing in solving cold cases and studies the impact that DNA fingerprinting has had on the forensic science community as a whole. The research is driven by studies and collection methods already implemented by the scientific community as well as future methods of collecting and testing DNA evidence as it relates to the investigation of unsolved murders.
From the Paper
"Adding to an already heavy burden, most states including California are attempting to take DNA samples from a prison population approaching 2 million. This DNA information is being used in order to create state and national DNA databases. "All 50 states have passed laws requiring collection of DNA from convicted sex offenders, and 34 states have enacted statutes requiring that DNA be taken from those convicted of other crimes." (Price) Although most are in support of creating such a database, others feel that it is a violation of the American Constitution. Additionally, many proponents of DNA in criminal murder cases feel that DNA is still an unproven science with many inherent flaws that could convict innocent people and allow some to literally get away with murder."

Abstract
In this article, the writer discusses DNA, which is short for deoxyribonucleic acid. The writer notes that the code contained within the DNA determines whether the organism turns out to be a fish or a dandelion, a person or a chimp. Further, the writer points out that it also creates the characteristics that make one individual similar to, but still different from, another. The writer explains DNA testing and notes that now that there are more reliable procedures, such as DNA testing, there are fewer people who are wrongfully convicted. The writer discusses convictions as they relate to DNA evidence.
From the Paper
"Wrongful convictions are not often talked about in the news, but they are occasionally mentioned when they are incredibly significant, such as a man who was wrongfully convicted 20 years ago and then was freed based on DNA evidence or some other new way of determining whether the person was actually guilty. These are the exceptions rather than the rules, but these do happen, and they can significantly affect the lives of many people. Not only is the life of the wrongly accused changed forever, but his or her family and friends are all affected as well. This is a very serious concern, and naturally the criminal justice system tries to avoid wrongful convictions as much as they can. It is not always possible, however, to avoid wrongfully convicting someone if there is a great deal of circumstantial evidence or if there are witnesses who claim the person is guilty of a particular crime."

DNA Testing on Death Row, 2002.
An argumentative paper in favor of allowing death row convicts the option of DNA testing to try and prove their innocence.

»
Click here to show/hide summary
Abstract
This paper argues that DNA testing should be available to prisoners on death row who maintain their innocence. This argument is based on three principles. The first point discussed is a scientific argument that DNA testing is one of the most reliable crime solving tactics available today. The second point is an economic argument, since state-funded DNA tests ultimately costs the taxpayers less than the appeals process and the costs of housing an innocent prisoner. Finally, the most important argument for DNA testing is moral. The writer states that making DNA tests available for prisoners would further the judicial process not only by helping convict the guilty, but also by exonerating the innocent.
From the Paper
"The use of DNA in solving crimes has become widely accepted. DNA is now routinely presented in courts as evidence. DNA evidence had helped to identify crime victims and has helped put criminals behind bars.
However, DNA evidence is also becoming valuable in another aspect of the judicial system. Increasingly, DNA testing is helping lawyers in defending innocent clients. In many cases, DNA tests have proven the innocence of many prisoners who have been in jail for years. This includes prisoners who would otherwise have been executed."

Abstract
The first part of this paper discusses the scientific merits of DNA testing and how these tests contribute significantly to forensic tests and criminal prosecutions. The next part of the paper discusses the precautions that must be taken to ensure that DNA testing is accurate. In the conclusion, this paper discusses how DNA testing should be used as a tool for criminal justice. In addition to using the tests to ensure guilt, this paper argues that DNA testing should also be a viable option made available for people who would like to prove their innocence.

Abstract
This paper discusses one of the most significant scientific discoveries of the twentieth century, the discovery of the helical structure of deoxyribonucleic acid (DNA). According to the paper, Watson revealed this discovery in his book, 'The Double Helix: A Personal Account of the Discovery of the Structure of DNA'. This paper reviews Watson's book and the fact that DNA was not discovered by a single person, nor by a group of scientists. The DNA discovery was the result of a complex series of advancements, discoveries and inspirations by many independent groups.
From the Paper
"Watson next goes on a series of European excursions and vacations; including being able to finally listed to Pauling. When he returns to Cambridge in the fall, Watson exhibits less preoccupation with DNA, and hears of the discovery by some bacteriologists that some bacteria actually reproduce sexually. This causes Watson to muse that the microbial genetics of them could be understood within a few years after DNA's structure is discovered. In the meantime, Watson writes that Franklin's X-Ray data "were getting prettier and prettier," (Watson 148). Furthermore, he credits her with obtaining the data indicating that the sugar-phosphate backbone of DNA was actually on the outside of the molecule; still, "She gave no sign . . . of liking helices any better," (Watson 148). Watson continues to explain his faith-based understanding of DNA when he writes, "The idea of the genes' being immortal smelled right," (Watson 153). After this leap of inference, however, Watson learns that Pauling is about to unveil another discovery regarding DNA; this worries most everyone at Cambridge. "
