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) "
Abstract This paper relates that scientists have deciphered every last one of the 3 billion DNA "letters" in the human body. The author points out that the completed DNAsequence is now expected to give scientists understandings about the workings of the human body that have never been made before. The paper stresses that this development will revolutionize medicine and biology.

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")."
Abstract This paper discusses use of DNA as crime scene evidence. Science has added a weapon to the crime lab's arsenal. From a drop of blood, strands of hair, or other biological material left at the crime scene, scientists can provide a much better "fingerprint", namely DNA.
Abstract This essay will explore the risks of DNA research and genetic cloning in the context of Michael Crichton's book "Jurassic Park". While this paper will recognize the benefits of DNA testing, its main argument will be that, while Crichton's book is somewhat exaggerated and unrealistic, the basic warning is legitimate: that there is a certain point where man's creation can hurt humanity itself.
Abstract This paper discusses how the courts have sent innocent people to prison as well as sentencing innocent people to death row. Most people would want the courts to use evidence that can correctly punish the guilty and set free those who are innocent. The paper further discusses how DNA evidence works to link the guilty with the crime they commit and it allows the innocent to go free. DNA as evidence is vital in making the right decisions about crime.
From the Paper "Imagine sending an innocent person to prison on charges that he or she did not commit, yet the courts have convicted and sentenced innocent people to death row. "There is no way to tell how many of the over 1,000 people executed since 1976 may also have been innocent" (Additional Innocence Information). The courts have sent innocent people to prison as well as sentencing innocent people to death row. "What if there was a way of typing a person to the scene of a crime beyond the shadow of doubt. Or, more importantly, what if you could rule out suspects and prevent the wrong person from being locked up in jail" (Meeker-O-Connell). "
Abstract This paper answers questions relating to DNA templates and the differences between the structure, function, and the treatment of viruses and bacteria. The paper also explains the necessity for making a template in the replication process.
From the Paper "The DNA has to be replicated so that after cell division each new cell will contain the full amount of DNA material. After replication every new cell will contain one strand of the original DNA plus one strand of the newly synthesized DNA. The original strand acts as template to guide the next process which is the synthesis of a..."
Abstract Modern ecological pressures are very different from those faced by early Homo Sapiens and other early hominids. Changes have taken place in DNA structures sometimes relating to our environment and our sociological issues. In the paper the author examines issues related to these changes and the results in Homo Sapiens and Homo Neanderthalensis.
From the Paper "Our four micro evolutionary forces; mutations, gene flow, genetic drift and natural selection have far different results in modern man and in fact the move from natural selection to self-domestication is changing man into some kind of pseudo robot form and the environment into a kind of pseudo self supporting bionomic. From hospitals who save the rare mutation that may have succumbed in nature, from importing and exporting to favor those with the 'wrong' genes in the 'wrong' area regarding gene flow, from the highly mobile human and his ability to intermingle with anyone around the world regarding genetic drift and back again to the doctors who save those that may succumb to natural selection; we have annihilated our four micro evolutionary forces into oblivion."

Summary and Conclusion
From the Paper "Genetic testing is also referred to as 'gene testing' and 'DNA tests' and is a process by which the individual's DNA is examined. DNA is the material which genes are composed of which serve to determine the specific characteristics of living things. DNA determines the individual's features and as well, genetic testing has the capacity to detect particular genes in terms of whether they are present, absent, or altered and specifically in detection of chromosome abnormalities through laboratory testing."
Abstract This paper looks at the discovery of DNA by James Watson and Francis Crick and other scientists. It describes the structure of the DNA molecule and how it replicates, how mistakes in replication are corrected, and how replication is semi-conservative. It then looks at transcription and translation, and gives an example of a 3 codon sequence, its DNA code, its mRNA translation, and the amino acids it codes for.
Abstract This paper offers an in-depth examination of the Human Genome Project. The paper first studies who the project came about, its leadership, funding and oversight procedures. Then the paper discusses how quality control is maintained and how information is shared and disseminated.
Abstract This paper provides an overview and discussion of the current state of genetic technology, with emphasis on the Human Genome Project. The microbiological aspects of genomic sequencing are briefly summarized. The focus is mainly on the ethical and social implications of knowing and understanding each gene. It also looks at how this emerging biotechnology is embedded into modern society through complex interactions between several institutions.
From the Paper "The project is a culmination of the application of the results of the past 50 years in genetics. Since the discovery of the structure of DNA (deoxyribonucleic acid), scientists have made two vital conclusions. The genome, containing an individual's DNA sequences, is a map for the physical and behaviourial traits that one has inherited. Therefore, a species' genome is the code to all of its biological faculties (Levi 6). In this sense, the Human Genome Project can be viewed as a necessary and central component to genetic progress, since complete knowledge of our DNA sequence is required to develop biotechnology that is more effective and on a broader scale."
Abstract This work seeks to examine genetic testing in the light of the potential contribution of genetic testing specifically in the area of forensic testing, predictive testing and carrier testing. The paper first defines genetic testing and then discusses its goals. The paper then looks at the potential benefits that can be gained from using genetic testing.

Summary And Conclusion
From the Paper "Genetic testing applications offer great potential in today's society from early detection of disease, to exonerating the wrongfully accused, to identifying criminals that otherwise would have gone on to other commission of crimes, to paternity testing and the new possibility of correction of genetic abnormalities and this is only to list a few. Genetic testing has opened doors for scientific, medical health and prevention, and social advances in quality of life as well as water and food quality measures. Genetic testing is greatly beneficial in today's society."

From the Paper "The deaths of thousands of innocent people can traumatize an entire nation, and this was the case on September 11, 2001 when terrorists attacked the World Trade Center and Pentagon. According to Gonzalez, Schofield and Schmitt (2006), "On September 11, 2001, 2,792 people were killed in terrorist attacks on the World Trade Center (WTC) in New York City. The number of victims, the condition of their remains, and the duration of the recovery effort made the identification of the victims the most difficult ever undertaken by the forensic community in this country" (p. 3). The use of deoxyribonucleic acid (DNA) as a means of providing virtually positive identification of victims of mass disasters is of fairly recent origin having been introduced about 50 years ago, but the impetus is on to use these techniques for a wider range of forensic applications. For example, during the 1990s, a number of states began to develop DNA identification programs, and in 1993, the FBI implemented CODIS, a national program designed to (a) support federal, state, and local law enforcement agencies in their creation of a population statistical database; (b) improve DNA forensic analysis methods; and (c) to serve humanitarian purposes such as the identification of missing persons or the human remains from mass disasters (Lyon, 2002). The FBI in particular favored the development of the CODIS application based on its "productivity and efficiency," but former director of the FBI crime laboratory John Hicks described the computer databank as "nothing more than an information management and screening tool" (Hoeffel, 1990, p. 527). The former director also indicated, though, that he expected that the initiative would ". . . save time and effort, and courts will have fewer cases to process because investigations can be better focused and coordinated" (FBI, 1991, p. 37). The CODIS application links the DNA profiles of convicts gathered by scattered state law enforcement DNA labs, encourages uniform standards, and pools DNA data to facilitate identification of criminals across borders (Lyon, 2002). The thirteen DNA sites used in the CODIS database are illustrated in Figure 1 below."
Abstract This paper discusses, in some detail, the way in which DNA is used for forensic purposes. The paper discusses DNA typing functions, its historical use in forensics and prosecution, the possible mistakes which may be made or encouraged by DNA typing, and the future of DNA in criminal and civic cases.

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."
