“Since 1963, tens of millions of babies have had blood drawn from their heals to be tested for rare diseases” (Timmermans). The Genetic Engineering, science of making changes to the genes, is developing as time passes. Technology such as genetic testing, cloning and gene manipulation are part of genetic engineering. The Genetic testing is a test that helps identify diseases or disorders by screening the genes. The cloning is process of creating copy of exact genes to create an organism with same exact gene copies. Lastly, gene manipulation is change of genes to create certain character trait in humans or animals. These kinds of technologies have different opinions by the public. It could be beneficial or dangerous to humans. The issue on use of genetic engineering is continually debated, while some argue that it helps prepare for possible disorders and may cure some diseases, …show more content…
People argue that cloning should or should not be permitted. Some people assert that animal cloning can lead to medical through and help with the endangered species. The article by Jenny Barchfield writes that “Brazilian researchers are turning to cloning to help fight the perilous decline of several animal species” (Barchfield). The scientists are trying to use cloning to help endangered animals from extinction. Cloning could help create an animal from endangered species to prevent the animals from extinction. This is very important to keep animals from extinction, because once they are all gone it is very hard to get them back. Another scientist states that cloning could be very useful to cure human from diseases.By producing organs from animals and transplanting it into human to cure the disease (Gardels). The cloning of animals could be also very useful to the humans. Using this technology could create an organ from an animal to transplant them instead of the diseased human organ to help cure the
When one thinks of cloning generally the first idea that pops into your mind is a large tube filled with some creature attached to a lot of tubes. Cloning actually, is a much more complicated and difficult process. Cloning, scientifically defined is, "asexual reproduction or as the creation of genetically identical individuals" (1). In the cloning process the DNA of one individual creature is "copied" into the cell, or embryo, of another and then that embryo develops into a baby and proceeds down the process of birth and embryological development. Currently, many scientists believe that if the DNA of endangered species is rescued and preserved that the DNA of that species could undergo the cloning process and thus produce a clone of that species. The results of this cloning process would be enormous or it "will open a new front in the battle to preserve the Earth's biodiversity by cloning endangered gorillas, tigers and other rare species" (2). Cloning of endangered species would be a monumental achievement for the scientific community. Many people when they think of cloning picture sometime weird science fiction creature in a test but in real life the idea of cloning could be a valuable tool for the environmental community and it would be a process could vastly improve the current situation of endangered species.
Human cloning research has once been the subject of terrifying science-fiction films and novels, science experiments gone wrong, accomplished only by the evil scientists twirling their moustaches. However, ideas presented on page and screen are rarely accurate. The possibility of cloning an exact copy of another human with one already fully developed is almost impossible, but through meticulous research, scientists have discovered the numerous benefits of cloning humans, either with individual cells or an embryo.
But on the contrary, many scientists believe that cloning can be such a positive achievement, not only for medical purposes, but for fighting extinction. For example, what if they could clone many of the endangered species that exist today? There are very few hundred of many beautiful animals that if something isn’t done to save them, they will be extinct in a few years. So if scientists could successfully clone and create these endangered species, although it would still depend on the clone maturing correctly and being able to reproduce successfully, it could be a great
Scientists also ponder the idea of cloning endangered species to increase their population. The possibilities of cloning are endless, however as suggested by (Hawley, 1998). actually doing much of this research for the improvement of life for humans. Cloning provides better research capabilities for finding cures to many diseases. Livestock can produce biological proteins that help people who have diseases including Diabetes, Parkinson's, and Cystic Fibrosis.
... of reproductive cloning is that in the future, it may be a solution to infertility, where a baby containing the genes of both parents could be artificially created, which will help the millions around the world who are unable to have children. Another benefit of cloning is that plants and animals can artificially be produced in large quantities directed at human consumption, which may, in the future help world hunger. Nutritionally superior or more “predictable” plants can also be created which will which will benefit us health-wise, and save farm costs. Lastly, the main advantage of cloning is that, through organ transplantation (therapeutic cloning), lives can be saved or prolonged, for those who have defective organs. For these 3 reasons, it’s a no brainer that scientists should continue extensive research and experiments for the better of our society as a whole.
Many people believe cloning is unethical and unusful. They believe that it should not be practiced, because it infringes upon their beliefs. They see cloning as a last resort and do not trust the science of cloning. “Several governments have considered or enacted legislation to slow down, limit or ban cloning experiments outright” (Freudenrich 5). Many people think that cloning a species is a very unideal situation. However the many benefits of cloning far outway the few disadvantages. Cloning endangered species is beneficial to saving most species around the world, in countries like the United States and China, from extinction.
“The question is not, can they reason, nor, can they talk. But can they suffer?” (Bentham). Each year over a hundred million animals endure a number of experiments in an attempt to make human lives easier. These experiments range from cosmetic testing to medical research, sadly neither of these tests are needed. Many people will accept animal research because they believe that these animals aren’t suffering (“Harm and Suffering”) or they believe that animal testing in beneficial to humans. In reality, these animals suffer for mankind, when the need does not exist. Animal testing creates unnecessary pain and suffering for animals, when in reality most experiments will not benefit human health.
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.
The topic I chose was cloning, but I will be focusing on Human Cloning. Dolly the sheep was the first mammal to be created using cloning technology in 1997. With the birth of Dolly the sheep it had raise of a possibility of one day being able to clone human. It took 277 times to create dolly the sheep although it suffers from arthritis and premature aging. In December 2002, a religious group of Raelin claimed that a human baby was cloned but it had not been scientifically confirmed. In 1962 John Gurdon claimed to have cloned South African frogs from the nucleus differentiated adult intestinal cells. In 1964, F.E Stewart grew a complete carrot plant using the carrot root cells and to prove that cell cloning was possible. Francis Crick and James Watson were the first pioneers to discover double helix structure of DNA in 1953. It increased the scientific research of learning about human genetic codes and discovers the possibility of cloning. According to Vos (2004), “In 1984, Steen Willadsun cloned a sheep from embryo cells, which were the predecessor to Dolly’s method of cloning.” In 2002 Boisselier chemist and CEO of Clonaid, cloned Eve the first baby to be cloned and was 7lbs; she is known to be a healthy and happy baby. Eve was created by an America woman of 31 years old who donated her DNA for a cloning process. The woman didn’t give her name, but her embryo was implanted and then gestated to the baby, with that it would make an identical twin as an exact genetic duplicate of the mother. The reason why she decided to donate her DNA was because her husband was infertile of resorted cloning.
For example, genetic engineering can be used to combat cystic fibrosis, which is a disease that damages the lungs and digestive system. Moreover, genetic engineering can be used to treat disorders such as diabetes as well. These two diseases, as well as much more, are one reason why people around the world are pushing for an increase in the research of genetic engineering. With the help of genetic engineering, people around the world who are suffering from incurable diseases have a hope to live pain and disease free. Furthermore, genetic engineers can look for mutated genes with preimplantation genetic diagnosis to tell if an embryo might have a mutation for trisomy 21 or Duchenne muscular dystrophy. If found, a scientist can potentially fix the mutation within the genetic code and therefore allow this embryo to grow to be a healthy child with no major health
Another area of medical advancement is genetic engineering. Genetic engineering will detect and possibly stop diseases before birth. Many diseases are associated with specific genes that can be checked for disease and replaced if dysfunctional. Genetic testing has already revealed genetic mutations that cause hypertension, heart disease, diabetes, osteoporosis, colon cancer, polycystic kidney disease, Alzheimers disease, and others. (5) Replacing missing, altered, inactive, or dysfunctional genes will prevent diseases or even death. Also, progression of a disease can be monitored, and
Human genetic engineering can provide humanity with the capability to construct “designer babies” as well as cure multiple hereditary diseases. This can be accomplished by changing a human’s genotype to produce a desired phenotype. The outcome could cure both birth defects and hereditary diseases such as cancer and AIDS. Human genetic engineering can also allow mankind to permanently remove a mutated gene through embryo screening, as well as allow parents to choose the desired traits for their children. Negative outcomes of this technology may include the transmission of harmful diseases and the production of genetic mutations.
The Problem Genetic engineering has been around since the 1960’s, although major experiments have not been really noticed until the 1990’s. Science comes in different forms, the two major being cloning and genetic reconstruction. Cloning is the duplicating of one organism and making an exact copy. For example, in 1996 the creation of the clone sheep named Dolly, the first mammal to be cloned, which was a great achievement. The other form, genetic reconstruction, is used to replace genes within humans to help or enhance the life of an unborn child for a medical reason or just for the preference of a parent.
Combine both animal and plant endangerment numbers, there are 23,000 animals and plants that are on the endangered list. Animal cloning will save endangered animals this should happen, soon when animals do become cloned, the 23,000 animal count, will fall! Within the next few paragraphs you will see how pleasant animal cloning can be! The Passenger Pigeon shall live again! Yes the Passenger Pigeon, will and MUST live again! Soon, all we need is time, and that is one of the duds that we all have in this world. We are able to bring back needed animals so should we bring back the pigeons or should we let them live on the extinct list forever.
Although genetic engineering seems to be more harmful than helpful, when used correctly, it will help the society prosper. Considering the technology our society has currently developed, genetic engineering is a difficult topic to discuss and confirm. If the researchers confirm this process, it may become easier for the scientists and will help cure the diseases easily. The debate, however, will still be on the rise because of the issue in human morals and ethics.
