The idea of cloning first came around in 1885. Cloning was first shown when Hans Dreisch in 1888-1894 took two and four cells of sea urchin embryos, isolated them and watched, as they became microscopic larvae. In 1901, Hans Spemann took a newt’s embryo with two cells and split them into two parts. The result of this was a clone of the larvae. In 1993, a human embryo was cloned for the first time, and then in 1996 Dolly the sheep was born. She was the first organism from adult cells ever to be cloned. Cloning has been practiced for many years and has many benefits ranging from the human health to scientific research. The United States government should deregulate cloning and provide more funding for research and development, as cloning is beneficial for finding a cure for cancer and many other degenerative genes.
Cloning is the copy of a biological entity; such as a gene, a cell, or an entire organism. Human cloning is defined by the American Medical Association (AMA) as the production of genetically identical organisms via the somatic cell nuclear transfer. Cloning human beings requires the DNA or the genes of the person to be copied and then a duplicate is genetically created.
There are two types of human cloning. There is therapeutic cloning and reproductive cloning. Reproductive cloning is when the cloned embryo is transferred into the uterus of a female of the same species, while the clone does not have a 100% identical chromosomal DNA as the genetic predecessor. Therapeutic cloning is used to help repair defective genes by the homologous recombination. As Professor Savulescu says...

...its research, so cloning should be deregulated and funded by the government. Other benefits of cloning are that it can give couples who cannot reproduce a chance to have children who are biologically related to them, whereas they would not be able to. This will also help those who are at a high risk of passing a genetic disease that they have. The parents could clone one of them and then reproduce a healthy baby with their genes. This type of cloning is called reproductive cloning. The reproduction through cloning is like any other common reproduction options and genetic-selection practices that it should not be treated any differently and be given to the recipients as an option. Cloning should be deregulated and funded by the United States government. The benefits and cures that come from human cloning are endless, and will benefits everyone in one way or another.
Cloning, upon first hearing the word cloning, the thought of Dolly the sheep pops into the mind. The first and most used type of cloning though is not the type that creates animals, but rather DNA cloning. “Cloning is an umbrella term that science uses to indicate the duplication of biological material.”(Human Genome Project) Cloning is further broken down into three categories. The first is DNA cloning, which is the replication of DNA strands. DNA cloning is usually the process of getting a cell to replicate a desired gene for us. DNA cloning has been used since the 1970’s and has persisted as an effective cheap means of replicating DNA of interest in a foreign host cell. “To "clone a gene," a DNA fragment containing the gene of interest is isolated from chromosomal DNA using restriction enzymes and then united with a plasmid that has been cut with the same restriction enzymes.”(Human Genome Project) Plasmids are not part of the chromosome but they replicate along with the cell when it replicates and divides. Since they are not a part of the chromosome they are easier to isolate and manipulate without affecting the cells function. “When the f...
Human cloning is the process by which genetic material from one person would be artificially transferred into a human or animal egg cell, thereby beginning the life of a new human individual who has only one parent and who is genetically identical to that parent. The once impossible idea of cloning became a reality in 1997 when Scottish embryologist Ian Wilmut and his colleagues at the Roslin Institute in Scotland announced that a cloned sheep named Dolly was born. Dolly was created by removing the nucleus from a sheep egg cell and replacing it in the nucleus of a cell taken from the udder of another sheep. This said might sound good, but there are other pieces of information that need to be known about this process. ...
The process of cloning may look like twenty-first century science but the history of cloning goes back all the way to 1885. Hans Adolf Edward Dreisch was the first person to ever demonstrate the process of artificial embryo twinning. By simply shaking a two celled sea urchin embryo he made a landmark discovery. When shaken the two celled embryos split apart creating two identical celled embryos. After the cells separated they grew into two sea urchins. This discovery proved two things, that embryos have their own genetic instructions, and have the ability to grow into a complete organism.
Cloning has been in nature for thousands of years, a clone is a living thing made from another consisting of the same DNA. For example identical twins are clones because they have the same DNA but the differ because the twins begin after conception when a zygote, a totipotent stem cell, divides into two, some plants self-pollinate and produce a seed, which in turn, makes plants with the same genetic code (Hyde). According to the Human Genome Project there are three types of cloning, DNA, therapeutic and reproductive; DNA cloning involves transferring DNA from a donor to another organism, therapeutic cloning, known as embryo cloning, involves harvesting stem cells from human embryos to grow new organs for transplant, and last is reproductive cloning which creates a copy of the host (Conger). One of the earliest cloned animals was a sea urchin by Hans Dreisch in the late 1800’s. Unlike Victor Frankenstein, Dreisch’s goal was to prove that genetic material is not lost in cell division, not to create another being, (History of Cloning) stated by Frankenstein “that I might infuse a spark of being into the lifeless thing that lay at my feet.” There are many ways an animal...
To start, it is important to understand what cloning is and the process that makes it possible. As defined by Merriam Webster’s Collegiate Dictionary, cloning is “one that appears to be a copy of an original form” (233). In layman’s terms, human cloning is using medical procedures to make an exact genetic copy of an already existing or previously existing person. The process for cloning entails a method called Somatic cell nuclear transfer, or SCNT. According to The University of Utah’s Genetic Science Learning Center the way SCNT is performed is “an egg cell's single set of chromosomes is removed. It is replaced by the nucleus from a somatic cell, which already contains two complete sets of chromosomes” (Genetic). Now that the egg has a complete DNA configuration, it is allowed to grow and the being that is engendered is a clone. Though the original human and the clone will have the same genome, they will not be exactly the same person. As Wray Herbert points out, there will be differences in personality an...
First and foremost, it is important to discuss what human cloning is. It is the conception of in vitro embryos that produces “individuals that are exact genetic copies of the donor from whom the DNA was obtained” (Munson 366). In Laymen’s terms, cells are inserted from the donor host into an unfertilized egg from another host (meaning it is asexual) and the new egg is transferred into the surrogate mother where it will foster into an embryo, if effective.
Cloning is, and always has been an extremely contentious topic. To some, the ethical complications surrounding it, are far more promiscuous than what scientists and medical experts currently acknowledge. Cloning is a general term that refers to the process in which an organism, or discrete cells and genes, undergo genetic duplication, in order to produce an identical copy of the original biological matter. There are two main types of artificial cloning; reproductive and therapeutic, both of which present their respective benefits and constraints. This essay aims to discuss the various differences between the two processes, as well as the ethical issues associated with it.
First, what exactly is cloning? In biology, cloning is used in two contexts: cloning a gene, or cloning an organism. Cloning is the reproduction of a human or animal whose genetic substance is identical to an existing being, such as an embryo or fetus. This is reproductive. Cloning a gene means to extract a gene from one organism and insert it into a second organism. Cloning an organism means to create a new organism with the same genetic information as an existing one. This is therapeutic.
Not so far in the future, a young boy of the age of six, dying a heart-wrenching death, will only be able survive with a bone marrow transplant. His parents will have searched near and far for a match, but none will come to their aid. The only possible way that they can produce a perfect match for their son's bone marrow is to clone their son. Unfortunately, at this time this topic is still being discussed and debated upon with the government. Their only child that has been their treasure for six years might die. A clone of their son becomes their apple of aspiration to keep the treasure from being buried.
In recent years our world has undergone many changes and advancements, cloning is a primary example of this new modernism. On July 5th, 1995, Dolly, the first cloned animal, was created. She was cloned from a six-year-old sheep, making her cells genetically six years old at her creation. However, scientists were amazed to see Dolly live for another six years, until she died early 2005 from a common lung disease found in sheep. This discovery sparked a curiosity for cloning all over the world, however, mankind must answer a question, should cloning be allowed? To answer this question some issues need to be explored. Is cloning morally correct, is it a reliable way to produce life, and should human experimentation be allowed?
Last of all, Cloning is not ethical, many religious groups look down upon cloning and think it’s not proper because they think it’s like playing God. Many scientists were mainly thinking about cloning animals and, most likely, humans in the future to harvest their organs and then kill them. “Who would actually like to be harvested and killed for their organs?” “Human cloning exploits human beings for our own self-gratification (Dodson, 2003).” A person paying enough money could get a corrupt scientist to clone anybody they wanted, like movie stars, music stars, athletes, etc (Andrea Castro 2005),” whether it be our desire for new medical treatments or our desire to have children on our own genetic terms (Dodson, 2003).
Cloning is a process by which genetically equal organisms are created with the same DNA. In simplest terms, clones are like twins born at different times. This procedure poses various dangers to society and humankind. One of the greatest threats this procedure creates is among
John A. Robertson’s article “Human Cloning and the Challenge of Regulation” raises three important reasons on why there shouldn’t be a ban on Human Cloning but that it should be regulated. Couples who are infertile might choose to clone one of the partners instead of using sperm, eggs, or embryo’s from anonymous donors. In conventional in vitro fertilization, doctors attempt to start with many ova, fertilize each with sperm and implant all of them in the woman's womb in the hope that one will result in pregnancy. (Robertson) But some women can only supply a single egg. Through the use of embryo cloning, that egg might be divisible into, say 8 zygotes for implanting. The chance of those women becoming pregnant would be much greater. (Kassirer) Secondly, it would benefit a couple at high risk of having offspring with a genetic disease choose weather to risk the birth of an affected child. (Robertson) Parents who are known to be at risk of passing a genetic defect to a child could make use of cloning. A fertilized ovum could be cloned, and the duplicate tested for the disease or disorder. If the clone were free of genetic defects, then the other clone would be as well. Then this could be implanted in the woman and allowed to mature to term. (Heyd) Thirdly, it would be used to obtain tissue or organs...
Recent discoveries involving cloning have sparked ideas of cloning an entire human body (ProQuest Staff). Cloning is “the production of an organism with genetic material identical to that of another organism” (Seidel). Therapeutic cloning is used to repair the body when something isn’t working right, and it involves the production of new cells from a somatic cell (Aldridge). Reproductive cloning involves letting a created embryo develop without interference (Aldridge). Stem cells, if isolated, will continue to divide infinitely (Belval 6). Thoughts of cloning date back to the beginning of the twentieth century (ProQuest Staff). In 1938, a man decided that something more complex than a salamander should be cloned (ProQuest Staff). A sheep named Dolly was cloned from an udder cell in 1997, and this proved that human cloning may be possible (Aldridge). In 1998, two separate organizations decl...
Human cloning is dangerous. It is estimated that between 95 and 98 percent of cloning experiments have failed (Genetics and Society). These downfalls to cloning are in the form of miscarriages and stillbirths (Genetics and Society). Cloned human beings also run the risk of having severe genetic abnormalities. Children cloned from adult DNA would, in a sense, already have “old” genes. These children’s main problem would be developing and growing old too quickly. This includes arthritis, appearance, and organ function. Since the chance of having a child with mental and physical problems is so much higher than that of a normally conceived child, cloning should be illegal.
