The Pros And Cons Of Dna Profiling
Nowadays, our modern life is becoming more comfortable and safe because of DNA (deoxyribonucleic acid). DNA is a genetic code that is made up of four chemical bases namely, adenine (A), guanine (G), cytosine (C) and thymine (T). Our body consists of about 3 billion bases and almost everyone has 99 percent of the same bases. Some organizations such as the Federal Bureau of Investigation, uses DNA and to help find and convict criminals. It is time-consuming to check and match DNA samples, but this can help the authorities to apprehend the real culprit. In the past, fingerprints, blood and other bodily materials in the scene of an offense were used by detectives in their investigation to catch and put criminals in prison but they were not foolproof methods. Wrongful convictions followed. But DNA …show more content…
Today, arguments for and against the use of DNA have surfaced.
DNA profiling is the technology that uses the individual’s DNA characteristics. Each human has his own DNA, comprising 99.9% of the same DNA but scientists have found the remnant 0.1% difference. One of its benefits is that scientists are using this crucial distinction to find criminals from bodily fluid samples, hair, skin and other parts of the body. (sciencemuseum, 2016)
DNA also has another advantageous application; it is used to find biological family relationships. In a Korean drama, the writer includes in his plot problems surrounding a family conflict. The father or the son gives his DNA sample such as found in his hair or toothbrush to the forensic scientists. Then, they

The more officers know how to use DNA, the more powerful a tool it becomes.” This proves that DNA evidence is very reliable and is hard evidence that cannot be argued upon. DNA is either found at the scene of the crime or isn’t.

744 Words | 3 PagesIt is a great technological innovation that can help bring evidences and fact faster. In the article The DNA Wars Are Over, “Forensic use of DNA technology in criminal cases began in 1986… In one of the first uses of DNA in a criminal case in the United States, in November 1987.” Sadly in 1985, DNA testing was not popular in the U.S. investigation and was not available in Cole’s case. I believe the U.S. court system is improving and yes there are a lot mistrials and wrongful conviction cases, but you cannot avoid the fact that DNA testing can bring better truth than just relying on statements of both
Trumps Science: The Case Of Picking Cotton
1247 Words | 5 PagesDNA has given some innocents their freedom, but others are still being locked up. Jurors are giving guilty verdicts to people who don’t deserve it based on theories and confessions that may have been beaten out of them. It was reported in the studies that exculpatory DNA does sometimes help a defendant that had confessed, but then prosecutors come up with theories and that doesn’t help the defendants, as was the case of Joseph Buffey (Appleby & Kassin, 2016). I didn’t expect for exculpatory DNA not to be taken into consideration when prosecutors told a theory that can explain why DNA of the accused was not at the scene of the crime. It just doesn’t make sense.

Analysis Of The Supreme Court Case Of Maryland V. King
980 Words | 4 PagesWithin our contemporary society, the Bill of Rights serves as symbol of the basic American freedoms and protects individuals from irrational government policies, which are not explicitly stated in the Constitution. In the Supreme Court case Maryland v. King, the culprit, Alonzo Jay King, utilized the Fourth Amendment after Maryland police arrested him for first and second-degree assault and swabbed his mouth to collect his DNA in order to check for any previous crimes committed. King argued that the practice of collecting DNA was unconstitutional because Maryland did not have a definite reason to analyze his DNA, as this intruded his privacy and that law enforcements would abuse the collection of DNA in order to convict people of unrelated
Phyllis Hennem Investigative Genetic Genealogy
1159 Words | 5 PagesToday, 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 PagesIn the lab report three students are tested along with one suspect. Student number two’s DNA matched the suspects DNA. The student’s DNA’s are cut with five different enzymes as well as the suspects DNA. Student two’s DNA matched exactly with the suspects DNA; the other two student’s DNA did not resemble the suspects DNA at all. (Choi, et al, 2008) DNA fingerprinting is used a lot in determining who committed a crime.
What Causes Wrongful Convictions
488 Words | 2 PagesOne of the most accurate methods of connecting a suspect with a crime is through the use of DNA analysis. Even if no fingerprints are left behind at a robbery, for instance, a single strand of hair or skin cell from the thief can be used to positively identify a suspect. Conversely, if a suspect’s DNA does not match samples procured from a crime scene, the use of so-called “genetic fingerprinting” can exonerate, or clear, them. Concern over the issue of wrongful convictions, coupled with a sense of greater trust in DNA analysis over other, more conventional methods of prosecution, such as eyewitness testimony, has led some to call for mandatory DNA testing before any person begins serving a sentence for a serious crime, as well as

Mentioned in the video, forensic science was developed by law enforcement, but DNA analysis was developed by medical science. A much more reliable source. There may be certain situations where DNA isn’t the best tool to go off of. Like for example if there isn’t an enough quantity of it at the scene of a crime or if it has been mixed with someone else’s (Kaye and Sensabaugh, 2000).
Importance Of Dna In Forensic Science
1251 Words | 6 PagesDNA in forensic science The majority of cells making up the human body are diploid cells carrying identical DNA, with the exception of haploid gametes and red blood cells. Several types of biological evidence such as blood and hair are commonly used in forensic science, which is the scientific study of evidence for crime scene investigations and other legal matters. Forensic science is used for the purpose of DNA analysis, this is the analysis of DNA samples to determine if it came from a particular individual. DNA analysis is done by obtaining DNA samples from an individual; next, a large sample of DNA is produced from amplified selected sequences from the DNA collected.
