Imagine a world where diseases can be found and prevented before they happen. This would be a future possibility if genetic engineering became more advanced. Genetic engineering is when parts of DNA are spliced into another piece of DNA which give new traits to the organism containing the DNA. Through continued research in the field of genetics, techniques such as mapping genomes and splicing DNA can be used beneficially to improve on existing organisms and their traits. To help understand genetic engineering, it is important to understand its history.
It was not until the industrial revolution that pollution and people’s negative effects on the environment became very apparent. New technology allowed for people to make changes that could possibly be irreversible upon the environment. With the culmination of drastic changes coupled by the advancement of technology, we have genetic engineering. Genetic engineering is both a threat and a benefit for humans in our continuous strive to manipulate the environment. The basic uses for genetic engineering include gene therapy, cloning, biological warfare, vaccines and antibiotic, human reproduction, and food production.
The study of genetics and the use of DNA fingerprinting pinpoints specific modifications and mutations that have resulted in evolutionary change. This has given historians, palaeontologists and archaeologists extensive evidence in the explanation of evolution... ... middle of paper ... ...d a resolution to these debates and has closed many gaps in the fossil record. The use of genetics is now being widely used in fields such as medicine, crime and archaeology. Farmers are now able to genetically modify crops to make them more disease-resistant and in turn, to ensure they have a better chance of survival. DNA analysis has led to breakthroughs in determining the true origin of many species and has also provided evidence to determine evolutionary change.
An efficient mechanism promising vast improvements to healthcare is the development of gene manipulation. Genetic engineering, also called genetic modification, is the direct manipulation of an organism's genome by using biotechnologies. The process begins with the molecular cloning of genetic materials or by synthesizing the DNA. The finished product is a new DNA sequence that then can be inserted into a host organism. Complete manipulation allows for the access to the gene.
It is a very serious and controversial matter because it raises many ethical, legal, and moral issues, especially in dealing with genetic engineering in human beings. There are generally three methods used in the manipulation of human genes and they are cloning, somatic cell manipulation, and human germline manipulation. Very basically, cloning is creating exact copies of an organisms DNA and creating a new organism with this same DNA. The new organisms will be physically identical to the original organism. Somatic cell manipulation is simply injecting new genes into somatic cells in order to cure a disease such as hemophilia.
Wouldn't it be great to improve health care, improve agriculture, and improve our quality of life? Genetic engineering is already accomplishing those things, and has the potential to accomplish much more. Genetic engineering, also referred to as biotechnology, is a fairly new science where the genes of an organism are modified to change the features of an organism or group of organisms. Genes are found in the DNA (deoxyribonucleic acid) of an organism, and each gene controls a specific trait of an organism. Scientists have discovered what many of these genes control, both in plants and animals.
This paper goes over genetic engineering and how it is used today in the medical field as two types on humans, disabled genetic engineering and trait genetic engineering. This two types of genetic engineering are still debatable since they have to surpass many obstacles and laws. The sources gave statements from professionals and experts on genetic engineering, biomedical science, biomedical engineering, and human anatomy and physiology. The individuals gave their inputs on how they view genetic engineering on human beings. Genetic Engineering: Engineering Humans With today’s technology, we are capable of doing countless features such as coming up with new medical innovations to treat diseases and other medical related issues.
- Ann E. Weiss Rapid advances in medical science have fuelled the question of bioethics. However, as science takes leaps and bounds towards its goals, ethics are often just learning how to crawl. In fact, it has even suffered major backslides in some cases. Genetic engineering "raises serious ethical questions about the right of human beings to alter life on the planet". Changing the basic physical traits of an organism can lead to an unprecedented threat to life on the planet".
In this way biotechnology and genetic engineering are linked. Genetic engineering should fall under biotechnology. My opinion is that Biotechnology should be researched further and be used but only to a certain extent. There a lot of extreme cases and many improvements to be made. I believe that biotechnology explores and opens up new avenues in biology that can definitely make a good difference in our changing world.
The Advantages and Disadvantages of Developing Genetically Engineered Organisms Genetic engineering is the method of changing organisms' characteristics inherited by alerting it genetic material. This often done to cause micro organisms, such as bacteria and viruses, to synthesize increased yields of compounds, to form entirely new compounds, or to adapt to different environments. Other uses of this such of a technology, is known as the recombinant DNA technology, it includes gene therapy, which is the supply of a functional gene to a person with a genetic disorder or with other diseases such as acquired immune deficiency syndrome (AIDS) or cancer. Genetic engineering involves the manipulation of deoxyribonucleic acid, or DNA. Important tools in this process are so-called restriction enzymes that are produced by various species of bacteria.
