The Pros And Cons Of DNA Profiling

975 Words4 Pages

Genetic fingerprint or DNA Profiling is a method of isolating and capturing images of the sequence of DNA. Alec Jeffreys, a British geneticist, developed this technique in 1984 after he discovered certain sequences of DNA, called minisatellites, which repeats within gene in a DNA sample; Jeffreys repeatedly notice the same observation for different DNA sample. He arrived to the conclusion of each organism contains a pattern of the DNA sequence that is unique to them, with multiple individuals from the same zygote, e.g., identical twins. In the United Kingdom, approximately 50% of the crimes are unsolved, approximately 159, 000 unsolved crimes. (Herbert, 2011) Most of them due to the lack of evidence, but if technology such as DNA profiling …show more content…

Five days later, Maria was abandoned by her abductors near the house of her maternal grandmother. Then a man released from a concentration camp told the grandmother that Monica has also been imprisoned there. In 1985, authorities of a new government questioned a policewoman who had worked at the camp; whom had a daughter she claimed as her own. Two years later, paternity test carried out by the new government’s Genetic Data Bank showed that the girl was in fact the daughter of Monica Lemos de Lavalle. (Lowrie and Wells, 1991) DNA fingerprinting is used for paternity/ maternity tests. Since the child’s genetic fingerprint is made up from half of each parent’s genetic information, this cause the child’s genetic fingerprint to match both of their parents. Sexual reproduction takes DNA from both parents together at random to create a unique combination of genetic material; therefore, the genetic material of a descendant is derived from the genetic material of both parents in equal amounts. However, DNA paternity tests are not 100% accurate and could lead to in accurate

Summary Of The Murder With No Body By Anita Larsen

207 Words | 1 Pages

Author, Anita Larsen, in her nonfiction textbook article “The Murder with No Body” about a murder solved without an actual victim writes to inform young adults about the role of forensics in solving crimes by using the case of Helen McCourt in a serious tone. This author supports her central idea very successfully. She supports her claim by introducing the case of Helen McCourt, whose disappearance was unexplained and suspicion of foul play could not be proven. She next proceeds to show that a name in the victim's diary led the investigators to blood stained clothes in the possession of Ian Simms, but the inability to prove that the clothes were McCourt’s halted the investigation. Additionally, she explains that the use of genetics had to

Why Was Richard Buckland Committed The Murder DNA Fingerprinting?

149 Words | 1 Pages

In 1968 genetic fingerprinting was first introduced into forensic science when solving two rape cases. The police were convinced that the rape was committed by the same person who committed a rape and then murdered the victim three years previous. Richard Buckland admitted to raping and murdering a 15 year old girl, but not to the murder that happened prior to this. So to try and identify who committed the murder DNA fingerprinting was carried out, they found that the semen collected didn’t match Richard Buckland’s so he was cleared of the murders.

Who Was She? A DNA Test Only Opened New Mysteries Libby Copeland, in “Who Was She? A DNA Test Only Opened New Mysteries,” discusses the increased popularity of DNA testing, the process, and the impact the results can have on the people who choose this path. In the article, Copeland effectively uses structure, tone, word choice and other rhetoric devices to establish her purpose of informing her readers about the effects of DNA testing. Copeland writes the article not only to inform, but also to engage and interest the general public, or anyone considering DNA testing.

Investigative Genetic Genealogy In the summer of 1976, Phyllis Henneman was awoken by a man in a ski mask in her Sacramento home. She was gagged, raped, and burglarized but survived. She described her life after that day as “irrevocably changed”, her “sense of safety was shattered”. Over the next decade, the burglar continued to terrorize Californians before escalating to “attack couples, tie up both victims, rape the female, and then murder them”.

Figurative Language In Libby Copeland's Who Was She? A DNA

979 Words | 4 Pages

Copeland carefully selects words in the introduction to emphasize an overall nonchalance in compiling such comprehensive information, “Over the past five years, as the price of DNA testing kits has dropped and their quality has improved, the phenomenon of ‘recreational genomics’ has taken off,” (Copeland). The use of “recreational” suggests the practice of gathering broad scientific information lacks gravity. In fact, the author contrasts the word with more levity with the use of “genomics”, a concrete science that affects the structure and function of genetic information. The dramatic usage indicates to the audience that users of DNA testing are incapable of understanding all possible consequences of accessible genetic testing. Traditions of past generations provide a foundation for the identity of future generations.

DNA Exoneration Case Study

547 Words | 3 Pages

Statement of the Problem DNA has become a vital part of criminal investigations. DNA can include and exclude suspects of criminal investigations. During a criminal investigation, all DNA should be collected, properly preserved and tested, but at times this does not occur or the technology was not available for this process to occur. In addition, DNA has become an imperative portion of exoneration cases.

Dna Fingerprinting Lab Report

1726 Words | 7 Pages

Although, in our lab report, suspect ones DNA matched the crime scene when cut with enzyme one, this can be explained by how closely related the two suspects are. Therefore two enzymes were used to cut the DNA; the suspect has to match both. Moreover, the limitation to DNA fingerprinting is, if a person were to have an identical twin. This is because identical twins have the same DNA because they come from the same egg. If a suspect’s DNA matched that of the one being tested, and they had an identical twin, a farther investigation would need to be done.

Dna Profiling Pros And Cons

DNA profiling poses a large threat to civil rights, and numerous studies have shown it is not close to being one hundred percent accurate. Each source provides strong and concrete information paired with real and theoretical examples. Additionally, the sources make their claims based on the same points: accuracy, indefinite storage of DNA, and the threat of genetic discrimination. While both sources are strong in factual content, the argument in opposition of DNA profiling is more persuasive because it goes into further detail to support why DNA profiling and creation of a central DNA database infringes upon constitutional

To avoid bias the lab team would not be informed of which twin is the real father. The twin’s blood, sperm, and buccal mucosa will be sequenced to look for SNPs in somatic and germ line cells. The sequences will be performed on a Illuminia HiSeq 2000. The mutations will be separated by chromosome.

The Pros And Cons Of Human Genome Research

1851 Words | 8 Pages

When Scientist looks at a genome they can find many things including diseases that may have been hidden in someone's genome. These are called recessive traits or genes. These traits are mutations in the DNA that are hidden or not shown in the carrier that can be passed down to the offspring of the carrier. These traits can include something as simple as the color of someone's eyes or hair to a genetic disease a parent did not know they had. If someone is a carrier of one trait and happens to have a child with someone else that is a carrier of the same trait,“there's a possibility of one in four, twenty five percent, of having an affected child” with that trait (00:13:26-00:13:31).
