Genetic Testing
… to refer to some type of medical test carried out to identify changes in genes, chromosomes or proteins. It is also known as DNA testing as it helps to detect changes in chromosome structure or DNA sequence. Over the past few decades, this biotechnology has become more popular to an extent that various genetic tests have emerged and expanded. ……

Crime Scene Management
...Dna The Importance of Effective Crime Scene Management
The purpose of this paper is to provide a review of the relevant literature to explain the importance of securing crime scenes in order to protect evidence from contamination and preserve it for use by the courts. In addition, a discussion concerning different methods that might be necessary to document evidence at a crime scene and different collection methods that might be used at a crime scene is followed by an explanation concerning the chain of custody and why it is important. Finally, the repercussions of failing to protect evidence or establish chain of custody is followed by an explanation concerning how an investigator or forensic expert differentiates between what is or is not evidence. A summary of the research and key findings concerning the foregoing issues are presented in the paper’s conclusion.

Can Aging Be Reversed
… at the most basic level of human cell lines.” Previous scientists had theorized that aging was the result of a mutation in the DNA structure. What the researchers in Japan discovered was that there was no mutation to be found: they compared the DNA of elderly persons with the DNA of 12 year olds and found the sequence structure to be the same. The only difference was reduced cellular respiration, which the researchers … the same. The only difference was reduced cellular respiration, which the researchers linked to epigenetic regulation—basically “changes that alter the physical structure of DNA without affecting the DNA sequence itself, causing genes to be turned on or off” (Mack, 2015). In essence, all that may be required to reverse the aging ……

Stephen Kings The Outsider Persuasive Argument
...Dna Stephen King’s The Outsider: A Persuasive Argument
Introduction
The Outsider is a well-written book with exiting and unexpected turns and twists. The book has several well-developed themes. In my opinion, however, the central theme of the story is the rational man’s inability to believe that which does not conform to reality – the inability to believe in the supernatural. It is important to note that one of the most celebrated traits of the modern man is rationality. In basic terms, rationality could be conceptualized as the ability to rely on logic or reason in decision making. This effectively means that from a rational perspective, anything that does not conform to reason and logic cannot be accepted. We all start off in life having outrageous beliefs and fantasies. For instance, as kids we believe in the tooth-fairy and regard Father Christmas as a real benevolent person. These are beliefs we outgrow……

Criminal Profiling Of Serial Killers
...Dna Does Criminal Profiling Work or is it Unjustified The Case of Tim Masters
Introduction
Criminal profiling allows law enforcement to develop their understanding of particular types of crime, criminals, criminal behaviors, and crime-ridden areas. The FBI’s Uniform Crime Reporting (UCR) Program is one data set tool used in criminal profiling (FBI, 2019). However, criminal profiling is not an exact science but rather more of an art and there is a high degree of subjectivity that goes into creating a criminal profile. Thus, when it comes to the criminal profiling of serial killers, there are many factors that must be considered—biological, sociological, environmental, criminological, and psychological inputs. This paper will describe what is involved in the criminal profiling of serial killers, how the process works, who conducts it, what traits of serial killers profiles tend to focus on, and how effective the process is at helping law enforcement agents catch killers.……

Scientific Method Applied To Forensic Science Paper
...Dna The Role of Forensic Science in Crime Scene Investigation
The scientific method begins with the identification of a problem. Questions are asked, data is collected, a hypothesis is formed and then tested. The scientific method is essentially no different from the kind of investigative work that investigators of a crime scene do on a daily basis. They a faced with a problem: a crime has occurred. The questions they must ask are: what happened, why, when, who was involved, where did it occur, and how did it happen? They collect data and using forensic science to analyze the data, they come up with a narrative that answers those questions (Shaler, 2011). Lab work helps to verify the story by providing more evidence that can give more details. This paper will show how the scientific method is applied to forensic science.
The forensic scientific method consists of five steps:

Hepatitis B Virus Infection
...Dna Hepatitis B
Hepatitis B virus (HBV) is a major public health problem across the globe as it contributes to nearly 1 million deaths annually. It is an infection that basically attacks the liver and has the potential to generate acute and chronic diseases. This communicable disease is mostly transmitted from mother to child during birth. Additionally, HBV is transmitted through contact with body fluids like blood. Since it is a life-threatening condition, the viral infection has received considerable attention in the healthcare sector. Healthcare professionals and other relevant stakeholders have developed various initiatives to help lessen the prevalence of this infection and mitigate its impacts worldwide. This paper analyzes this communicable disease, determinants of health relating to its development, epidemiological triad, and role of the nurse practitioner in the management of the infectious disease.
