collected from vaginal swabs conducted through DNA analysis. Unfortunately, no suspect had been…

Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) make up the nucleic acid in cells and is responsible for the differences in many of our traits. DNA is the substance in which our genetic material is carried on from one generation to the next. Nucleotides join together through phosphodiester linkages between the 5 ' and 3 ' carbon atoms to form nucleic acids. “Nucleotides are composed of a five-membered sugar group with a purine or pyrimidine nitrogen base group attached to its 1 ' carbon…

dedicated to storing DNA profiles of individuals. The primary purpose of a DNA database is to ease the identification process of suspects during criminal investigations. Despite the intention to do good, the concept of a DNA database is vulnerable to a number of complications and repercussions, affecting the government, general public and crime detectives. Biological Significance DNA Profiling is a forensic process utilised to identify individuals by the characteristics of their DNA. It…

Mandatory DNA Testing Policy: Many disciplines of forensic science, including DNA analysis, are undergoing change in the United States and around the world. The validity and accuracy of older and even current methods are being challenged. New approaches for interpreting evidence via probabilistic modeling are being introduced. A better appreciation of difficulties that can exist for the field of forensic science is gained when the diverse cultures of scientific laboratories, law enforcement, and…

DNA testing which can also be label as DNA fingerprinting, DNA profiling and even DNA typing is considered a forensic technique that can be used to identify a person by their characteristics of their DNA. (What is DNA Testing?, 2016). DNA testing was developed in 1985, to identify a suspect and placed that initial suspect at the incident location during the time of the crime. DNA testing have evolve in the past decade that is can be used to study the animal populations. DNA testing can collected…

the structure of that DNA that it's shaped like a twisted ladder and understood the way it replicates. b) Rosalind Franklin- She discovered the dimension of DNA strand and that the phosphate group was on the outside of the helical structure. c) James Watson- Together with Francis they discovered the structure of DNA and that he also discovered that hydrogen bonds were the correct length and were straight. 2. All of the three scientist were interested on working on the DNA and so the were all…

James Watson, Francis Crick, Rosalind Franklin and Maurice Wilkins all played a pivotal role in determining the structure of the DNA molecule. The orderly and methodical work at King’s college, London by Rosalind Franklin and Maurice Wilkins provided a more experimental approach, working closely with X-ray diffraction images of DNA, this was juxtaposed to Watson and Cricks who at their Cambridge lab approached research by building physical models, narrowing down possibilities and producing ever…

1.2 Cellular DNA Damage responses, genomic instability. DNA is the blue print of life and all the information of life processes such as growth, metabolism, reproduction etc are encoded in the sequence of it. Therefore its very important to maintain the genomic integrity of this genetic material, not only to keep away defects in life processes but to pass a faithful information to the next progeny. Integrity of the DNA is usually challenged by both endogenous and exogenous agents who are capable…

Assessment - DNA Technology DNA Profiling Forensic Identification Forensic Identification refers to the use of forensic science to identify objects from trace evidence found on them. Trace evidence is used to reconstruct crimes or accidents. DNA profiling is a method in forensic science which can identify individuals by their DNA profiles. DNA profiles are encrypted sets of letters that represent a person’s DNA makeup. These sets can be used as a person’s identifier. Although 99.9% of…

In observing the preceding decades following the first use of DNA analysis through technology in 1986, the criminal justice system has manifestly prioritized this specific high-tech DNA evidence in every case following the discovery. Maurice Wilkins once said “DNA is like Mida’s gold, everyone who touches it goes mad,” and in this case it corresponds fittingly. As the material that accompanies the process of DNA technology progressively becomes further “professional” and more frequent, criminal…
