Dna Fingerprinting Report

861 Words4 Pages

This experiment used the process of DNA fingerprinting to determine which suspect committed a specific crime. Although the results were null due to lab time expiring, the lab TA gave the information out that suspect 3 committed the crime. This is due to his/her DNA fragments matching that of the DNA found at the crime scene more than the other two suspects that were tested. Introduction: This experiment was carried out to determine which of three suspects committed a crime by using the processes of DNA fingerprinting. There are two stages of DNA fingerprinting, the Polymerase Chain Reaction (PCR) and the treatment of restriction enzymes (Polymerase Chain Reaction (PCR) (Theory) : Molecular Biology Virtual Lab II : Biotechnology and Biomedical Engineering : Amrita Vishwa Vidyapeetham Virtual Lab). PCR can amplify a single or several fragments of DNA which is significant because if the piece of DNA is too long, it is not able to be used in this lab. Restriction enzymes help compare DNA between suspects by cutting its palindromic …show more content…

With that being said, their DNA fragments that were created from the restriction enzyme used, had to be a match. I hypothesized that suspect 3 would be a match which was supported by the results given by the lab TA. What should have happened in this lab was effected by the time limit given. If there was more time or if we had begun sooner, the results would have been easier to explain. The significance of this experiment was to show how DNA fingerprinting is essential to forensic science. In 2014, DNA fingerprinting helped put a man in Iowa behind bars 40 years after the murder happened by matching blood found on the victim’s blanket to that of her killer’s blood that was found in the national felons’ DNA database (Bovsun,

The samples from one victim were too deteriorated to be conclusive, but the samples from the other victim’s vaginal swab and underwear were subjected to PCR based DNA testing and it showed no match to Richard Cotton. At the request of the defense, the results were sent to the State Bureau of Investigation’s DNA database, containing the DNA patterns of convicted felons in North Carolina prisons. The DNA proved to be a match for the convict who earlier confessed that he was the one who actually committed the

It can refute a claim of self-defense and put a weapon in the suspect's hand. It can change a story from an alibi to one of consent. 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.

Unfortunately, police and interrogators can twist the whole case around and convict an innocent person and may never even find the actual person who committed the crime. DNA testing is a powerful way to see who committed the crime. However, fingerprints are never the same, even for the same person, and like the example in the article told, there could be a twisting of the story. They might say oh the blood does not match you five, there must have been a sixth person and you five did not bleed on the victim. Even DNA testing can make innocent people commit to being guilty.

Stories about the use of DNA evidence to convict offenders or exonerate defendants in criminal cases have become increasingly common in the recent years. Forensic DNA technology is transforming the way law enforcement officers investigate crimes, especially violent ones. DNA has an extremely important role in criminal trials due to its power of exoneration of innocent individuals. Many wrongfully convicted individuals, but later exonerated by DNA evidence, falsely confessed or made an incriminating statement. This can be seen in the Earl Washington case as presented by Frontline.

The Pros And Cons Of Fingerprinting

1172 Words | 5 Pages

Fingerprinting is method based on the uniqueness of the skin pattern - that is, each person has a completely individual pattern of papillary lines. These patterns do not change throughout life and have the property of recovering from damage to the skin in its previous form. On the one hand, this method almost completely eliminates the mistake, and on the other hand it is very cheap and easy to use (in contrast the method of identification of a person by DNA). Fingerprinting allows: 1) to identify the person who left the prints, according to the general and particular features of the papillary pattern displayed on them; 2) to exclude individual from among those who have touched the object; 3) to narrow the group of individuals suspected of the particular crime (for instance, provided that the imprint shows traces of a scar, a burn, a wart or some other distinctive feature).

Dna Fingerprinting Lab Report

2151 Words | 9 Pages

The lab focuses on DNA fingerprinting which is usually done in forensics to catch criminals by the analysis of DNA fragments of different sizes by a method called electrophoresis. Electrophoresis is a separation technique that uses an electric field to separate and distinguish biological molecules (this including DNA) in the experiment, gel is used to as a way to apply friction in electrophoresis which can help you easily distinguish between the DNA because of different sizes in the DNA confirmations. The goal of the experiment was to identify between two separate suspects DNA with restriction enzymes that help tell apart the suspects and who was actually at the crime scene. The methods used were the use of a gel made from agarose placed in a gel tray connected to an electrical current because of the DNA being negative and being able to be pulled apart to the positive side and therefore getting a clear spread of the DNA that was cut with restriction enzymes. The conclusion of this experiment was that suspect two was the criminal because of the crime scene DNA that was found matched the DNA of the second suspect when cut with

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 Fingerprinting On Trial Summary

1152 Words | 5 Pages

DNA Fingerprinting on Trial is an article written in 1989 by Ian Evett, Peter Gill, and two others. The article begins by introducing what DNA is and discussing briefly what restriction fragment length polymorphisms (RFLPs) are, as well as how they are measured with an electrophoresis gel. According to the authors, forensic RFLP testing at this time was being “pioneered” by two laboratories and used by the FBI. The authors then go on to say they believe “the scientific community [has] failed to set rigorous standards to which courts, attorneys and forensic-testing laboratories can look for guidance.” Essentially, the authors think that the techniques used in 1989 for forensic DNA analysis are inadequate and they discuss certain situations in

Argumentative Essay: The Growth Of DNA Profiling

1313 Words | 6 Pages

DNA profiling is a method that is becoming more popular in criminal investigations because of how the method can guarantee a DNA match. Unlike other methods, DNA profiling can take a DNA sample of a suspect and give an identity, because with DNA profiling the method uses all types of records to find the identity, not just the records of past criminals. The use of all of these different records helps in case the suspect’s match is a guarantee and not just someone with a past criminal record, whose DNA is similar to that of the actual suspect (Pros and Cons). Another reason why DNA profiling is becoming more and more popular in criminal investigations is because DNA profiling can use a wide range of DNA samples. In other methods of finding a DNA match,

Eyewitness Testimonies

Eyewitness testimonies has contributed tremendously towards law enforcement and crime, helping to place the accused behind bars for the crimes they have committed. Although it has helped to place a huge number of these accused behind bars, eyewitness testimony has been proven to be rather inaccurate and unreliable (Brigham, Maass, Snyder, & Spaulding, 1982). Through the advancement of technology, DNA evidence has proven that some of these individuals have been wrongfully incarcerated. DNA evidence may be an effective measure, but it would only help to solve a minimal number of cases when DNA samples present. At times, DNA evidence might only help to prove that the individual is present at the crime scene.

The increasing use of the DNA testing technology and the technology getting more and more advanced, a number of cases of wrongful conviction have been resolved and the innocent victims have been freed from incarceration (www.innocenceproject.org). The study by Scheck et al. , (2000) depicted that among a pool of 2000 prisoners around 62 victims were released using the evidence from DNA testing and across these 62 cases, 15 (24%) involved the instances of false confessions. As the project continued the number of exonerated innocent prisoners rose to 188 by 2006, December with 45 cases of wrongful convictions arising due false confessions again (www.innocenceproject.org).
