Animal Cloning Controversy

The first Mammal to be cloned was Dolly the sheep. That’s when cloning really started to take off. Dolly lived from 5 July 1996 to 14 February 2003. Since the cloning of Dolly just over 20 years ago, 22 other species of animals have been cloned since. ("Cloning Dolly The Sheep") (“How many

Genetic cloning is one of the most controversial topics of all time. People, specifically scientists, are constantly searching for ways to improve the quality of human life. As a result, they began genetically engineering animals and are currently in search of a method to genetically engineer humans as well; which is called human cloning. There are many reasons why people should not go forward with this step since genetic cloning, consequently human cloning, does not respect nature nor does it ensure diversity and survival in natural ecosystems. In addition, genetic cloning is a cruel, harsh, and an unsafe experiment.

According to Kathleen R. Brooks and Jayson L. Lusk (2011) Animal cloning is a process in which scientists can copy the genetic or inherited traits of an animal.

Cloning is a biological process of making genetically copy it would be copy of a single cell or whole animal. The first mammal cloned Dolly the sheep. There are three types of cloning: they are (1) the recombinant DNA technology or DNA cloning or gene cloning, (2) reproductive cloning, and (3) the therapeutic cloning.

Numerous attempts are being made in the hopes of finding an answer to the problem of the millennium. The concept of cloning has caught scientists attention throughout this past century. "The world has to come to grips that the cloning technology is almost here,” a representative for a European research group, Panos Zavos. Clones are life forms that have identical genetic coding. A clone is an organisms replica. Originating in the late 1880’s; the first record of synthetic embryo

However, natural cloning is not the only example of identical copies seen in the world. Artificial cloning is the more common example used in science. There are three commonly known “types of artificial cloning: gene cloning, reproductive cloning and therapeutic cloning” (“Cloning Fact Sheets”). These types of cloning provide identical copies of many biological aspects such as genes and larger segments of DNA. Gene cloning is “creates copies of genes or segments of DNA” whereas reproductive cloning “creates copies of whole animals” (“Cloning”). Finally, therapeutic cloning “creates embryonic cells” which are used in the hope of growing healthy tissue (“Cloning”). Animal cloning has helped many scientists to better understand genomes and review genes/DNA. In the

The controversy of human cloning has contemplated the reasons it should or shouldn't be allowed. Human cloning is the reproduction of human cells and tissue by creating a genetical copy artificially. Clones contain original characteristics of the individual or cell. There are many dangerous risks and great benefits to human cloning. Many people have an extraordinary reaction to cloning because it creates all sorts of images. Cloning is a medical breakthrough that can help millions of people if it is scientifically proven to be 100% safe. Is science really ready to officially clone a human?

As mentioned earlier, cloning is the copying of an organism that results in identical offspring (“Cloning”). Scientists have tried cloning many times on frogs and other organisms (“Cloning”), but when the first mammal to be cloned was successful in 1997, scientists jumped into pools of thoughts to clone humans. The first mammal to be cloned was a sheep named Dolly. The process of cloning Dolly was called Somatic Cell Nuclear Transfer. The nucleus of a somatic stem cell is taken out of the eggs of the

They took a cell from an adult sheep’s udder and extracted the DNA. It was then put into a “blank” cell. This was the first time an adult cell had been used instead of an embryo cell. Adult cells do not have as much DNA as embryo cells. After 277 attempts an embryo was finally produced. Six days later the cells were transferred into a surrogate mother. The pregnancy progressed like normal and Dolly, named after singer Dolly Parton, was born on July 5th, 1996. Dolly lived for six years, which is only half the lifespan of a normal sheep. Dolly even had lambs. This first cloning led to many discussions about the morals of cloning. Animals cloned can have various health defects. The discussion even was presented that if humans were cloned they would lack personality and emotions. While humans haven’t been cloned great gains have been

The ethical concerns with cloning didn’t become a problem until Dolly, the sheep, was created. Many years before Dolly very similar experiments were being performed; however, those experiments did not spark much public concern regarding cloning. Over fifty years

The science in biology allows us to discuss living things, organisms, and the creation of life. The United States banned all kinds of cloning in 2005, but there is still a curiosity in if it can lead to improvement in human existence. Cloning is about composing an identical organism out of the given DNA and constructing it to appear as natural as it originally did. Experiments and approval for human cloning may be in many years to come and out of reach today. As far as animal cloning, we know to a point it’s safe. If we continued the exploration in genetic replication on species, breeding animals can enable us to provide food for a growing global population, and save endangered species. An article like Dolly the Sheep’s Fellow Clones, Enjoying Their Golden Years, the writer brings attention to cloning as being a possible answer to the problems we harbor

There are three types of cloning; reproductive cloning, genetic cloning, and therapeutic cloning. This report will focus on reproductive cloning. Reproductive cloning is the duplication of an existing organism’s genetic material. Once duplicated, the organism is an exact copy of the original organism.

Single celled bacteria has the ability to replicate an identical offspring; this process is asexual reproduction. Humans and mammals can also have natural clones. In humans we call them identical twins, these twins have almost have the same genes as each other, but are naturally different from their parents. Genes are a unit of heredity that are passed from parent to offspring, that can also be cloned. However cloned animals do not always look alike. For example, the first cat cloned was a calico that is very different from the adult cat. During cloned birth the female adult gives birth to an animal that has the same genetic makeup as the animal that donated the somatic cell. There are some drawbacks to cloned birth, some effects are; an increase in birth size, defects in the liver, defects in the brain, and also defects in the

Many Americans do not understand how risky it will be to clone a human, not to mention how hard it is to clone an animal. Many news article and publications offer this information to the public, because many scientists will not address the media with the real facts. In an article titled, “Creator of cloned sheep, Dolly, says he wouldn’t want to make copies of humans”, Dr. Wilmut stresses that only 1-5% of those embryos used in cloning result in live animals, and survivors are plagued with obesity, kidney problems and other troubles, and even Dolly is suffering from arthritis (1). Most cloned animals, like cows, pigs, goats, sheep, die during embryonic development, and others are stillborn with monstrous abnormalities. Bloated mothers have laborious miscarriages, and occasionally die themselves. The clones usually struggle for air in intensive care units, only to have to be euthanized, the process of ending the life of an individual suffering from a terminal illness or an incurable condition, according to an MSNBC article titled, “Much confusion over cloning” (1). The risks and uncertainties associated with the current technological state of cloning are the basis for why

Animal Cloning Debate A clone is a genetic copy of another living organism –animal, plant or human. Animal cloning is a widely discussed issue in our society today. The question now is whether the Australian government should ban animal cloning. Many opinions are generated from this subject, such as the justifiability of cloning, and how far it should go.
