Genetic Engineering is the rearranging of genes in the DNA strand. The history of genetic engineering can be traced back to historic times. Animal and plant breeders have found ways to alter and change genes to their advantage for thousands of years. For example, “yeast fermentation was used to manipulate the seeds.” (Aldridge) But the actual science of genetic engineering came much later. Genetic engineering is based on genetics, a science started from the early 1900’s.
Michael Pollan's Putting It Back Together Again: "Processed Foods" Initiative 522 on the Ballot 2013 Let's start off with what are GMO's? It's an acronym for the scientific term for Genetically Modified Organism. What is a genetically modified organism, it's anything that as been altered from it's original state. All plant life has it own DNA makeup just like we humans do. When the original or natural organic plant life has been modified they can make crops 4 times larger than a naturally grown crop, they can even modify the plant can be genetically altered to have a pesticide to ward of insects that would normally kill off crops.
139. Outline the events which led to the acceptance of DNA as genetic material. Student number-130182904 Word count-2000 INTRODUCTION The quest to identify and define the nature of heredity had begun before the discovery of DNA. Charles Darwin took the first step towards the ‘biological revolution’ through “The theory of evolution” which, however, only described how heredity operated in large populations of living beings1. It was only when Gregor Mendel published his paper on “Experiments in Plant-Hybridization” in 1865 that the process of heredity came down to individual organisms1, 2.
Allison Maio Designer Babies Two million years of human evolution has led to the types of humans we see today. Everywhere around us are humans that are very different from each other with imperfections. On a not too distant horizon, advances in biotechnology will allow scientist to engineer the specific genetic makeup of our children. The term 'designer baby' made its entry into the Oxford English Dictionary in 2004, where it is defined as "a baby whose genetic makeup has been artificially selected by genetic engineering, combined with in vitro fertilization to ensure the presence or absence of particular genes or characteristics. My concern is the altering of embryos would destroy what it means to be human.
The practice of experimenting on animals goes back many centuries. “As early as the 2nd century AD, Roman physician Galen experimented on pigs and apes to demonstrate that veins carry blood, not air, as had been believed. In the early 1600s English physician William Harvey studied diverse animals such as worms, insects, fish, and frogs, providing pioneering insights into the principle by which blood circulates in the body.” (Archibald) Use of animal experimentation increased significantly in the 1800s, impacting the rapid development of science during that century. “In the 1970s the animal rights movement gained new momentum and visibility, particularly with the 1975 publication of the book Animal Liberation, by Australian philosopher Peter Singer, which called animal experimentation morally indefensible. In many incidents during the 1970s and 1980s, protest took the form of late-night raids on research facilities.” (Phillips) During the 1970s and 1980s, protest took the form of late night raids on research facilities.
I actually find that very interesting in the fact that through the major advancements in the medical field, scientist have successfully found vaccinations for diseases that have killed millions, robots that perform surgery, cloned animals, and the list could go on and on. But science has provided no solid evidence on how the universe got its beginning. Many philosophers and theologians believed that the existence of the universe needed an explanation. Plato (c.427-347 BCE) and Aristotle (c. 384-322 BCE) were among the earlier philosophers who attempted to answer the question in what became known as the cosmological arguments. According to Plato in his dialogue “The Laws” he argued that motion in the world and the cosmos was “imparted motion” that required some kind of “self-originated motion” to set it in motion and to maintain that motion.
FDA in Biotechnology One of the most controversial scientific advances have to do with people just like you and me. A newfound ability of extraction of a gene within the DNA strand has stirred up conversations between scientist all over the world. A surprising amount of people would actually prefer not to enhance their child's intelligence and strength, which is actually now possible before the birth of the baby. Just like “Designer Babies” the topic of cloning is very controversial as well. Cloning happens when the DNA of an embryo is extracted completely and then the DNA of the cloney is inputted into the embryo to have an exact replica of himself an example of this would be Dolly the sheep, Dolly only lived 6 years.
China is just as bad with there one child only law. “If you're going to wipe out 20 percent of your population, nature is not going to sit by and watch.” (Freiberg 13) The part about nature not just sitting by and watch reminds me of Jurassic Park. In the movie the dinosaurs where to be all female but eggs were found, nature found a way to rebalance the dinosaurs by changing the sex of some of them. This was due to the amphibian DNA that was used to fill in some of the genetic code. Amphibians are prone to changing sexes in an unbalanced environment.
Genetically modified foods have been surrounded with a lot of controversy and now thanks to science, practically every feature of your unborn child can be controlled or chosen. A designer baby is an infant that is the result of genetic engineering coupled with vitro fertilization to ensure the presence or absence of a specific gene in the infant and therefore thee child will only contain the chosen qualities from the parents. The technique involves the use of In Vitro Fertilization which fertilizes eggs together with sperms in a lab. This is used to produce designer babies who are free from hereditary diseases. Researchers have been able to find that the method cures rare diseases that affects at least two out of five thousand people around the world (Brownlee).
Animal Cloning and Experimentation | March 22 2011 | logan ward | logan ward PHI 110 | A question that has plagued scientific and philosophical minds for many years is whether the experimentation and cloning of animals is ethical. This same question has caused more questions to arise again and again; such as, should we exploit animals for our own benefit? Do our rights override that of animals, and if they do, should we be allowed to decide the fate of these animals? Furthermore, what are we to do with these animals when we have cloned them or when we have finished our experimentations on their cells? Are these clones really animals, or are they just scientific facsimiles?
