  • Pros And Cons Of Dna Profiling

    1329 Words  | 6 Pages

    DNA profiling was first established in 1985, and has seen extensive use in the field of forensic science and genomics. DNA profiling was developed in 1984 by Alec Jeffreys, after he noticed that certain sequences of highly variable DNA, which were non-coding, were repeated within genes (McKie, 2009). He recognised that each individual has a unique pattern of non-coding DNA sequences therefore allowing them to be profiled. The process has helped the police in solving crime cases over the years, as

    1509 Words  | 7 Pages

    DNA Forensics is the application of DNA technology and the knowledge of DNA genetics to the practice of forensic investigation and to the power of legal process. It involves various analytical techniques that can be used for the analysis of DNA.

    809 Words  | 4 Pages

    Since the dawn of DNA testing in 1985, skin, hair, blood and other bodily fluids have become the most reliable physical evidence collected from a crime scene, especially in a sexual assault. DNA (deoxyribonucleic acid), contains the genetic blueprint that differentiates each person. Forensic testing determines if distinctive patterns in the genetic material found at a crime scene match a suspect's DNA with better than 99% accuracy (James 2009). Tommie Lee Andrews from Florida became the first person

    1. What is DNA? DNA i.e. Deoxyribo Nucleic Acid is a material in the human body that determines the hereditary traits of a person pertaining to hair colour, eye colour, skin, body structure, viability to diseases etc. DNA is located in the cells of the human body, wrapped in structures called chromosomes. A person inherits is DNA, 50% from his mother and 50% from his father. Any genetic disorder in an individual is usually due to mutations in this DNA. It is an established fact that the each person

  • The CSI Effect: The Use Of Forensics

    760 Words  | 4 Pages

    The CSI Effect has been caused by the popular television show "CSI: Crime Scene Investigation" and has given viewers an unrealistic view regarding forensic scientists, the use of forensics, and the criminal investigation itself. Forensics has become a rapidly growing field and has only been applied to criminal investigations since the latter part of the nineteenth century. The earliest use of forensics can be traced back to the Bertillion System created by Alphonse Bertillion of the Paris

Shlomit Avraham maintains that “the success of obtaining DNA profiles from touch DNA has opened up possibilities and led to the collection of DNA from a wider range of exhibits” (Avraham 793). How many people have been released or imprisoned due to faulty accusations? Where are DNA samples found

    size of the blood spatter? Police use many different scientific techniques to solve crimes such a murder cases. They dust for fingerprints, use special lights to look for blood, use chemicals to find out what mysterious substances are, and sample DNA. And in addition to figuring out who did it, they have to figure out how he did it. And to do that, they often use a technique called blood spatter analysis. Blood is primarily made of water and as such, it behaves much like water and therefore must

    Introduction   DNA: Deoxyribosnucleic acid is the hereditary materials in humans, almost all DNA is located in the nucleus, some is found in the mitochondria (mtDNA).   Genes: Everyone is different, like our fingerprints, our genes differ too, this is greatly benificial in solving crimes as a lock of hair, drop of blood, etc, all of this allowing the police to link everyone involved into the murder, ensuring the right person is punished for the crime. There are two main types of genes, phenotype

  • Using DNA Evidence Analysis

    However, the using of DNA evidence to judge the offender has to be used very careful. It is possible that the DNA evidence from the testimony is planted. For example, the O.J. Simpson case that the lab officer planted the DNA evidence. The American Supreme Court ruled out that evidence because it was obtained from illegal doing, even if it is proved that it’s the Simpson’s blood. Simon A. Cole note that the Simpson case was not concerned with only the admissibility of DNA evidence but also was
