The Department of Justice says, "States began passing laws requiring offenders convicted of certain offenses to provide DNA samples. " That DNA evidence can help convict someone of a crime and it helps to uncover more things about the crime itself. Investigators have been using forensic science to help them solve cases since before the 90 's, mostly fingerprints that were found at the crime scenes and on the victims (O 'Brien). DNA evidence has solved countless cases including ones that happened over a prolonged period of time because of the technological advancements there is
Historically, forensic science and miscarriages of justice were never closely examined. However, forensic science has been pointed to as a contributor to miscarriages of justice since as long ago as the Dreyfus case. The Dryfus case or the “Dryfus affair” was a political scandal that divided France until it was resolved in 1906. It started with the treason conviction of Captain Alfred Dreyfus, a young French artillery officer of Alsatian and Jewish descent. Sentenced to imprisonment for sharing French military secrets to the German Embassy in Paris.
Biotechnology is the manipulation of living organisms and their components to produce useful products for humans. This new technology is shocking and impressing the world than ever before through movies, TV shows and video games. As the world grows, this new technology is starting to become more useful day after day. An excellent example of the use of this technology can be seen in the movie Jurassic World. In the movie, they used many different types of biotechnology like PCR (Polymerase Chain Reaction) to copy fragments of the dinosaur’s DNA, and genetic engineering to give it certain traits not common in all species of dinosaurs.
By entering the latex prints for cases into a database and then requesting a match on a certain set, the program would run through all fingerprints logged into the system until hitting a match. Additionally, this program also links crimes together if the prints belong to the same individual. The most dramatic change in crime scene investigation and forensic lab technicians is in the modern day DNA capabilities. In the seventies, investigators and forensic analysts would collect blood, hair, and other sources of evidence with the technology and procedures available, which were poor due to lack of technology. When DNA first became available, the collected evidence pertaining to such (blood, semen, hair) was sent to DNA labs but the technology was inadequate, and required more substantial amounts in order to run such diagnosis.
Animal biotechnology is the application of biotechnology in processing and production of several materials by animal or aquatic species in order to improve human life. Scientists use biotechnology to overcome some of the major global problems since several decades ago including the food crisis due to the sharply increase in human population, health and disease and conservation on some endanger species. Cloning is the biotechnology used to produce genetically identical copies of a biological entity. The copied material, which has the exactly same genetic makeup as the original, called a clone.
Biotechnology is a new age of science. It can both be a blessing and a curse. What do you think? Biotechnology can both advance us medically and agriculturally, making the world better. Biotechnology is a scientific involving the manipulation of living cells to produce useful products (source 1).
Biotechnology may lead to poisonous crops, sickened patients, and major overpopulation, therefore should only be considered a risk and harmful to the
Biotechnology, specifically, genetic modification, are viewed in a particular way. GATTACA is a movie about creating an eugenic society where people are genetically modified at birth- inheriting the best traits of their parents- to conceive the “ideal” man or women(Niccol, GATTACA). Before Vincent Freeman was born, his younger brother- Anton, was genetically modified to be tall, strong, and have no possible diseases(GATTACA). In other words, Anton was genetically modified in a society where eugenic is favored. This scene emphasizes the aspect of biotechnology that genetic modification is an useful technology.
Most people that don't have much knowledge in biotechnology think that it is ethically wrong or bad for us humans. Biotechnology can solve many problems in our world. Biotechnology is genetically modifying something, like a person's genes, food, etc. This biotechnology could change our world for the better, but never the less there are risks, and science doesn't have all the information on it yet. Biotechnology can create a better world to live in.
Pros of Biotechnology Biotechnology has many pros about it. It has the ability to remove diseases like mental disorders in human fetuses. It can help save the populations of animals such as cows , goats , and chickens. It can make healthier foods , from meats to plant foods like cucumbers and apples. It can also help make vaccines for viruses such as the flu.
DNA technology is the study of genetic material. Scientists are now using DNA technology for a variety of purposes, for example cloning. Cloning is the process of making multiple or identical copies of a gene. DNA technology has had major impacts on agriculture, disease therapy, crime scene investigations and the pharmaceutical industry. But like anything in science it also has its ethical, legal, and social concerns that play a major part in our applications today.
Definition: Biotechnology is the usage of naturally occurring biological processes, systems or organisms to create or modify products, such as antibiotics, intended to improve the quality of human existence [1]. Biotechnology is divided into four main practices: Red, White, Green and Blue biotechnology. Red biotech is concerned with medical disciplines. White is the industrial application of biotech. Green considers agriculture.
Introduction Biotechnology is the use of biological systems or organisms to create products or perform processes that are beneficial to mankind. Broadly, this entails any form of manipulation to biological organisms and systems. Even though lab related biotechnology expanded in the late twentieth century, following the discovery of Deoxyribonucleic Acid (DNA) in 1953, much older biotechnological techniques and processes had already existed. These include beer production, biological pest control and domestication of plants and animals; including selective crop farming and breeding of livestock. Following the exponential growth in the field of biotechnology many societal, ethical and legal issues have emerged.
Science and technology are the fastest growing industries in the world and will always be. Reason for this is that human beings are constantly seeking ways of making life easier and function efficiently while producing quality work and leading a high standard of living. Much improvement has been seen in the agricultural sector with more genetically modified foods been produced to meet the overwhelming demand for food coming from the rapid growth of the world’s population. This investigation, was not only intended to answer whether genetic engineering could be regarded as biotechnology; but most importantly it was to note that not every scientific improvement aimed at helping human beings is necessarily beneficial, at least not completely.
DNA 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.
