The Dna And Its Impact On The Society

This paper explores deoxyribonucleic acid (DNA) collection and its relationship to solving crimes. The collection of DNA is one of the most important steps in identifying a suspect in a crime. DNA evidence can either convict or exonerate an individual of a crime. Furthermore, the accuracy of forensic identification of evidence has the possibility of leaving biased effects on a juror (Carrell, Krauss, Liberman, Miethe, 2008). This paper examines Carrells et al’s research along with three other research articles to review how DNA is collected, the effects that is has on a juror and the pros and cons of DNA collection in the Forensic Science and Criminal Justice community.

DNA forensics is a division of forensic science that focuses on the use of genetic material in criminal investigation to answer questions pertaining to legal situations, including criminal and civil cases. Through DNA testing, law enforcement officers are able to identify human remains or the individual responsible for a crime. DNA testing is a highly advanced scientific process that involves replicating the human DNA sequence to create a genetic map of an individual. Because of its reliability, DNA testing has become a significant factor in criminal cases. However, it has also been identified as having the potential to violate privacy and constitutional rights. The DNA identification process consists of five stages. These five stages

Deoxyribonucleic acid, or DNA as it is most commonly known, is a strand of molecules found within the cell nucleus of all living things. It is called a “genetic fingerprint” because each is different to the other and everyone, apart from identical twins, have

However, the video Race: The Power of Illusion presents significant evidence refuting the biological theories of race. Cold Springs Harbor Laboratory instructor Scott Bronson and several high school students from different ethnicities conducted personal genetic research exploring biological race theory. Students’ typed their blood, compared skin tones and took DNA samples. After sending the samples to a genetics lab, Bronson asked students whom they might expect to be more genetically similar to in the workshop. The consensus of the students was that they would each be genetically comparable to others in the group with similar physical attributes.

Additionally, there is a substantial lack of real evidence that the divisions between groups that we often specify as “races” actually have specific genetic identities. The extreme presence of ambiguity central to races, and the plentiful variations within these races point towards evidence that even two randomly selected citizens of European descent could be more genetically related to a person of Asian descent than they are to each other.

This paper explores the history and some interesting facts about DNA. The last couple centuries have seen an exponential growth in our knowledge of DNA. The history of the DNA can be traced back to multiple devoted scientist. This article attempts to summarize, and review the basic history of DNA while providing some fascinating information about it.

The meaning, significance, and definition of race have been debated for centuries. Historical race concepts have varied across time and cultures, creating scientific, social, and political controversy. Of course, today’s definition varies from the scientific racism of the eighteenth and nineteenth centuries that justified slavery and later, Jim Crow laws in the early twentieth. It is also different from the genetic inferiority argument that was present at the wake of the civil rights movement. However, despite the constantly shifting concepts, there seems to be one constant that has provided a foundation for ideas towards race: race is a matter of visually observable attributes such as skin color, facial features, and other self-evident

Before the 1980s, courts relied on testimony and eyewitness accounts as a main source of evidence. Notoriously unreliable, these techniques have since faded away to the stunning reliability of DNA forensics. In 1984, British geneticist Alec Jeffreys of the University of Leicester discovered an interesting new marker in the human genome. Most DNA information is the same in every human, but the junk code between genes is unique to every person. Junk DNA used for investigative purposes can be found in blood, saliva, perspiration, sexual fluid, skin tissue, bone marrow, dental pulp, and hair follicles (Butler, 2011). By analyzing this junk code, Jeffreys found certain sequences of 10 to 100 base pairs repeated multiple times. These tandem

Deoxyribonucleic acid (DNA) has been used to analyze and prove innocence or guilt of suspects of crimes with great accuracy. DNA is part of everyday life. It is the heredity material in humans and almost all other organisms. While being part of an investigation. DNA has helped to solve crimes. There is a couple ways that DNA left behind can be tested to solve a crime. Either if the suspect has been caught and or had his or her DNA tested, or if he or she has left behind any biological evidence. Which then needs to be tested to see if it matches the DNA found in the crime scene to his or hers DNA. The result to this comparison may help establish if the suspect committed the crime.

DNA Fingerprinting, also known as DNA Profiling, is a method used to identify a person using DNA patterns that are specific to him/her. 99.9% of DNA is identical in every human being, but .01% is enough to distinguish between people. It is most commonly used in criminal cases to link a criminal to his/her crime scene, but is also used for paternity/maternity tests, and immigration records. Usually a skin, hair, or body fluid sample is collected from a crime scene or criminal or test candidate, then DNA is extracted and cut using enzymes that recognize patterns in DNA and run through a gel by an electric current in a process called electrophoresis (Annely).

Allowing the annual report of the National DNA Database Strategy Board as of 2012-2013, NDNAD helps the law enforcement in giving worthful information that will lead in determining the suspect and solve crime cases. However, sometimes the crime doesn’t solve and more evidence needs to be collecting to secure a conviction but in dealing with NDNAD it provides the police of its needed information for DNA matches.

What is DNA? Is it these winding strands that look like ladders or is it what gives a person blonde hair and blue eyes? Actually, DNA is both of these things. DNA is a person’s genetic makeup–their hereditary blueprint passed on by their parents. It is a part of almost every cell in the human body. In each cell, a person’s DNA is the same; it stays the same throughout their lifetime. DNA is found in skin tissue, sweat, bone, the root and shaft of hair, earwax, mucus, urine, semen, and vaginal or rectal cells. The DNA found in a person’s saliva is the same as the DNA found in their blood. Parts of the DNA determine our physical characteristics, such as eye and hair color, height, and bone structure, but the

DNA fingerprinting is a technique that is used to determine how likely it is whether genetic material came from a specific person or family group. Since 99% of human DNA is identical, that means that it is only 1% of our DNA which is different, and it is that 1% that we look at when we are attempting to determine the origin of a DNA sample.

When mammalian DNA is injected into the body, dendritic cells are not stimulated. Moreover, it also failed to elicit appreciable antibody response even when it coupled with a protein carrier and presented in adjuvant (Madaio et al., 1984). This failed action is quite the opposite of animal disease models that are stimulated by immunization with protein auto-antigens such as experimental allergic encephalomyelitis or collagen-induced arthritis, inferring that DNA is different from other biomolecules in its immunological properties. Various studies, including from our lab (Dixit et al., 2005; Tripathi et al., 2014) as well as from others (Al Arfaj et al., 2007) propose that the DNA molecule undertake structural changes leading to the formation of new epitopes or neo-epitopes that are recognized as foreign by the immune system and are able to bring out antibody responses. However, when single stranded DNA is used for immunization, it can bring a restricted antibody response, and other helical nucleic acid species including double stranded RNA, RNA-DNA hybrids, carcinogen or drug modified DNA or complexes of DNA with proteins that can bind DNA are considered to be effective immunogens (Stollar, 1975; Anderson et al., 1988; Desai et al., 1993; Moinuddin and Ali, 1994; Dixit et al., 2005; Khan et al., 2006; Tripathi et al., 2013). Due to the presence of distinctive sequence motifs, bacterial DNA can induce the immune system to generate antibodies to sequential rather that backbone
