Have you ever thought that science can advance rapidly to a great extent? Nowadays scientists are trying to make the same exact copy of your DNA. Can you imagine having a clone of yourself, your parents, or even your siblings? Have you ever wished for someone to take your place for a minute, an hour, or a day? This may come true one day. According to the Online Dictionary; a clone is defined as “a cell, cell product, or organism that is genetically identical to the unit or individual from which it was derived.” I always thought that cloning was impossible, and is just science fiction.
The process of cloning is the creation of genetically identical copies of a biological unit. This means that every single part of the DNA is identical. The natural way of a clone is identical twins. In nature, twins occur just after fertilization of an egg cell by a sperm cell. Then when the fertilized egg, a zygote, tries to divide into a two-celled embryo, the two cells separate. Each cell continues dividing on its own, eventually developing into a separate individual within the mother. Another natural way of cloning is when single celled organisms, for example bacteria, produce genetically identical offspring. This process is called asexual reproduction. Asexual reproduction is the formation of new individuals from the cells of a single parent. Cloning is accomplished without the contribution of two gametes; therefore it is an asexual reproduction.
There are three different types of artificial cloning, molecular cloning, reproductive cloning and therapeutic cloning. Molecular cloning, which is also gene cloning, produces identical copies of genes or DNA. Reproductive cloning produces copies of whole animals. Therapeutic cloning is the...

...ly believe God breathes life into each person not science.
On the other hand, if cloning is not limited to certain copies it can be tremendously harmful, since cloning means making the same exact copies of a cell. Scientist in the future can make many copies of a person with the same exact genes. Those copies can be a population, and if one of them is sicken, the whole population will die. Cloning humans is a hard step for scientists to take which might result in taking the lives of innocent people.
Overall, cloning produces the same genetic copy of DNA. As science and technology advances, cloning plants, animals, and human organs will be much safer and helpful in many ways. As the Cloning topic advances it stirs up more and more controversies. Even though cloning is against my religion, I hope one day that it will help people and animals that are in need

Essay on Pros and Cons of Human Cloning - Cloning is a process in which genetically identical copies of biological matter are created through nonsexual means. Clones are made up of organisms that are exact genetic copies. Every piece of their DNA is identical. Cells, genes, tissues and entire organisms can be created through cloning. Aside from cloning being done in a lab, clones do happen naturally. Identical twins are just one natural example of cloning. Cloning has been used for many years. The earliest examples of cloning have been associated with plants....   [tags: Human Cloning Essays]

Essay on Genetic Engineering: Cloning: Dolly and Eugenics - Cloning is vital in American society because it will help us further our knowledge in genetics. Also cloning will make us realize how much scientists can actually accomplish knowing how to clone. Scientists were able to clone an animal in 1997. That accomplishment made all the scientist’s theories about cloning possible. It gave the scientists hope that one day they will maybe be able to clone a human because they were able to clone a mammal. Eugenics is also vital to American society. Eugenics is the practice of improving human’s genetic quality of the human population as a whole....   [tags: dna, science, god]

Essay about The Benefits of Animal Cloning - The Benefits of Animal Cloning Put yourself into the body of someone who is need of a vital organ. You are on a waiting list, but who knows when you will receive this precious organ. The doctor says the chances of receiving an organ donor are slim because of your rare genetic make-up. The thought of praying for another human to die, just so you can live, seems selfish, but today, the only way to receive an organ is from the death, or the chance of death, of another human being. Even then, the donor may not match....   [tags: Cloning Argumentative Persuasive Argument] 2001 words

The Debate of Human Cloning Essay - Missing Appendix The Debate of Human Cloning Human cloning has become a hot topic for debate. As we progressed one step closer to successfully cloning and developing a human being, legislators and the general public have become more concerned about the ethical and moral implications of this procedure. The federal government has been unsuccessful in reaching an agreement as to what policy to pass and enact. Thus, any current legislation on human cloning has been developed and enforced by individual states....   [tags: Cloning Clones Science Genetics Essays]

Essay about Cloning - Well, Split My Embryo! - Cloning – Well, Split My Embryo. Genetic engineering, altering the inherited characteristics of an organism in a predetermined way, by introducing into it a piece of the genetic material of another organism. Genetic engineering offers the hope of cures for many inherited diseases, once the problem of low efficiencies of effective transfer of genetic material is overcome. Another development has been the refinement of the technique called cloning, which produces large numbers of genetically identical individuals by transplanting whole cell nuclei....   [tags: Cloning Argumentative Persuasive Argument] 621 words

Cloning Essay - It all started back in the fifties when James Watson and Francis Crick discovered the structure of DNA (D’Souza NA). Ever since there has been talk of human and animal cloning. It all seemed out of reach and basically impossible, but in 1997 that all changed when a sheep, named Dolly, was the first ever mammal to be cloned. She was cloned for the purpose of curing disease and research on animal organs for human transplantation (Schaeffer 3). Now that scientists know that it is possible to clone literally anything with DNA, the world has become a rather scary place....   [tags: DNA ]

Essay Cloning - Why ban cloning. For one, the many deformed, stillborn, diseased and dead animals created on the way to making Dolly. As must as we’re being told that human cloning is just around the corner, in fact, even the scientists who are most successful at cloning have a very poor track record making cloned animals. (5) Although cloning experts claim that their work would help infertile couples, the experience with animal cloning has shown that scientifically, the experiment generates ethical concerns just as it is still replete with a lot of risks for the offspring....   [tags: essays research papers] 466 words

cloning Essay - Introduction The possibility of human cloning, raised when Scottish scientists at Roslin Institute created the much-celebrated sheep "Dolly" (Nature 385, 810-13, 1997), aroused worldwide interest and concern because of its scientific and ethical implications. The feat, cited by Science magazine as the breakthrough of 1997, also generated uncertainty over the meaning of "cloning" --an umbrella term traditionally used by scientists to describe different processes for duplicating biological material....   [tags: essays research papers] 2721 words

cloning Essay - Since March 1997, the birth of a cloned sheep, named Dolly, has caused a great sensation around the world. The reason why Dolly shocked the world was that she was the first clone from a cell of an adult mammal: something scientists thought to be impossible. The cloning of a mammal cell meant that the possibility of cloning a human beings was increased. For fear human cloning, a lot of countries have taken necessary measures to regulate the study of it. We should ban human cloning because it has the possibility to reduce the value of human life: taking away individuality in our society....   [tags: essays research papers] 1022 words

Cloning Essay examples - Cloning For hundreds of years man has wondered what it would be like to clone human beings. With the idea of cloning comes many different opinions and positions. The idea of creating an army of "super humans" has long been a dream of many people. Others have feared what would happen to the world if cloning were possible and if cloning is morally correct. Overall, religion and ethics play a vital role in the both of these viewpoints and greatly effect many positions on the topic of cloning....   [tags: Essays Papers]
