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.

Today, the FBI has DNA records of more than 5 million convicted offenders in the database CODIS, or Combined DNA Index System. However, DNA fingerprinting has limitations: it is limited to directly connecting crimes to felons already in CODIS, has high risk of contamination, does not look at familial records, and only analyzes short pieces of DNA. With the advent of more affordable and high resolution genetic technologies after The Human Genome Project, over 35 million people have submitted their DNA to the largest direct-to-consumer genetic companies. Two companies, FamilyTreeDNA and GEDmatch, also allow law enforcement access to their databases. Thus, beginning investigative genetic genealogy, a new method of forensic investigation not only with higher resolution DNA information than DNA fingerprinting but also the capability of finding a suspect from distant relatives.

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.

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.

Dna Profiling Pros And Cons

714 Words | 3 Pages

Serious issues, both positive and negative, arise when DNA profiling is used to identify suspects and/or individuals potentially involved in crimes. Ethical issues are most often related to the storing of DNA profiles in a National DNA Database. Not only does this database include DNA information from suspected criminals, it contains DNA information from victims, volunteers and suspects who were not deemed guilty. DNA is the genetic make-up of a person’s body and many people argue whether it is fair or not to keep such private information in such a large database as this, especially those who had nothing to do with the crime. “It is debatable whether the benefits to society of having a national DNA database outweighs an individual’s right to

In my opinion through the evidence shown throughout the years DNA sampling should be collected on the first offence. Privacy and the right to your own body are important, but the right to feel safe from your attacker is also important. Collecting DNA samples would reduce the crime rate, free those who have been wrongly convicted, and finally give justice to those attacked by putting those criminals behind

Argumentative Essay: The Use Of DNA Evidence In Courts

Deoxyribonucleic acid (Dna) might sound like the miracle that made Spiderman, and that is by no means false, because DNA is what made and will make every single living creature on this planet. DNA is what makes us all unique, whether your brothers, sisters, cousins, parents and children. The world is busy debating many scandalous topics, however, only a few share the same importance, as the matter considering the use of DNA as a source of evidence in courts. Based on the research that I conducted, I recommend the use of DNA in courts but not as a sole piece of evidence, but an important part of it. DNA is a debated for suggestion mainly because of the extreme reliability it offers.

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).

Dna Profiling Essay

Introduction This essay will discuss DNA profiling, in particular the history of DNA profiling, types of DNA analysis and DNA data bases amongst others. DNA profiling is a useful method to aid in forensic sciences, in identifying people who may be potential criminals. It is the method used to identify individuals based on the unique sequence of nucleotides in each person’s DNA (de Fontaine, 2013, p. 8).My aim is to establish whether or not DNA profiling can lower the crime rate in South Africa. South Africa is still listed as a third world country and may or may not have the means to use DNA profiling as a forensics tool. History of DNA profiling
