Cloning Is The Creation Of The Genome Of An Organism

Clone: â€Å"Strictly speaking, cloning is the creation of a genetic copy of a sequence of DNA or of the entire genome of an organism.† In simple, easy to understand words, cloning is the process of making an exact replica of an organism. After doing a bit of research, the Stanford definition of the word clone stood out. The most used and known method of cloning is somatic cell nuclear transfer or SCNT. In SCNT the nucleus of a cell from the intended duplicate is transferred from the original cell and into an immature ovum. In this process, the ovum gets the majority of the DNA from the original cell. This oocyte, or immature ovum, is then hit with an electric current, and the cell divides into two. This makes the cell â€Å"believe† that it is a recently fertilized egg. These two are the result of an embryo that is essentially identical to the parent cell; therefore, it is a clone to the somatic cell donor. In 1996, the first mammal ever cloned was a sheep named Dolly, born in February, 1997. Dolly was an exact replica of her cell donor on the outside. Scientists everywhere were given proof, for something that seemed scientifically impossible was in fact possible and had been done. After a while, this excitement died down. As the lamb continued to develop many problems came and at the young age of six, Dolly died. Dolly aged faster than the other sheep around her. One theory behind this is that she aged faster because she had genetic makeup older than a fertilized egg. She also gotShow MoreRelatedThe Shortcomings of Cloning1152 Words   |  5 PagesThat is where cloning begins as well, with a singular cell, more specifically a DNA cell. A clone is an organism that is an exact genetic copy of another organism (Barber, 6). Francis Crick and James Watson discovered that DNA is made up of two strands, called a double helix (Barber, 9). Maurice Wilkins, James Watson, and Francis Crick won t he 1962 Nobel Peace Prize for their DNA work. There are approximately 3 billion DNA base pairs in the human genome (Barber, 10). In the human genome, there are 20Read MoreGenetic Engineering : Genetically Modified Organisms Essay1293 Words   |  6 Pagesmodified microorganisms are microorganisms/organisms which have been genetically altered meaning that their genetic materials have been modified. This modification is achieved through a technological method, genetic engineering. Genetic engineering also known as recombinant DNA technology/genetic modification is a science that employs molecular biology techniques so as to modify or alter the genome of an organism. It involves manipulation of an organism’s genome directly by use of biotechnology. TypicallyRead More Cloning Technology: With Respect to Faith and Reason Essay1642 Words   |  7 PagesCloning Technology: With Respect to Faith and Reason Church VS Science The idea of sitting in an airport and seeing someone walk past that looks identical to you may seem absurd, but due to new scientific development it may not stay that way for long. In 1953 two scientists by the names of James Watson and Francis Crick discovered the structure of DNA.1 DNA can be defined as the makeup of chromosomes, which carry genetic information. DNA is present in nearly every living organismRead MoreReport on Therapeutic Cloning1109 Words   |  4 PagesArgumentative Paper - Therapeutic Cloning A sheep named Dolly is the first thing to come to mind when the term cloning arises. Everyone remembers the hoopla or has read of the hoopla that surrounded the birth and survival of the first successfully cloned animal. This is because cloning, to some, is a questionable practice at best. In general terms, cloning is the replication of another animal. It is a process whereby an identical twin is created in a lab. However, cloning is not limited to replicatingRead MoreThe Creation of Synthetic Life Forms1216 Words   |  5 PagesThe creation of synthetic life forms: the science, benefits, risks and ethics. The creation of a synthetic life form is the production of an artificial autonomous self-replicating organism under in-vitro conditions from biochemicals. Synthetic life experiments and creation of synthetic cells gives us an unparalleled insight into the origin of life, the fundamental genes and essential genetic functions required for life and may someday allow the manipulation of the roles of cells and organisms toRead MoreGenetic Engineering : The Field Of Human Biotechnology1490 Words   |  6 PagesGenetic engineering, also called genetic modification, is a set of techniques for isolating, transforming, multiplying and recombining genes from different organisms. Simply put, it is the process of manually adding new DNA to an organism. Genetic engineering originated in the 1970s as a result of the discovery of several key techniques in molecular genetics. It is also referred to as recombinant (rDNA) technology. Genetic Engineering enables geneticists to transfer genes between sp ecies that belongRead MoreHuman Cloning Essay1608 Words   |  7 Pagesare the new lab specimen. Human cloning is like opening Pandoras Box, unleashing a torrent of potential evils but at the same time bringing a small seed of hope. No matter how many potential medical and scientific benefits could be made possible by human cloning, it is unethical to clone humans. Before the ethics of human cloning can be discussed, the mechanics of cloning must be understood first. Cloning is the process of making an exact genetic copy of an organism by a method called nuclear transplantationRead MoreCloning Stem Cells From Cloned Embryos Case Study1693 Words   |  7 PagesWould this not further dehumanize the resulting organism if it were to reach full development and thus make research and creation a more desentistized approach to the â€Å"subject† or â€Å"research clone†? So can we then move to a society which creates a personalized approach to cloning? One that accepts perhaps cloning for the purpose of therapy, rehabilitation, replacement organs and so on rather than focusing on reproductive cloning. Personalized cloning therapies are likely to be labor intensive and expensiveRead MoreEssay about Human Genome1485 Words   |  6 Pages GENOME PROJECT Adam and Eve were doomed for trying to be like god, this is the same damnation mankind is headed to. Everyone’s dream is to have absolute power and control of everything. The genome project and DNA engineering gives man the ability to create life and cu omize life to his specific needs of likes. So how good is too good? Man’s ability to make life or create perfect human beings so they can be in a state of Utopia will disturb the balance of nature. Every individual, every childRead MoreCloning Is Not Without Opposition1278 Words   |  6 PagesCloning is a vital technology that humanity should strive to perfect, despite the many obstacles it currently faces in development and application. Approximately 100 species become extinct a day. Among them are flora and fauna that could hold the cures for cancer, HIV, or any other disease. Cloning technology could preserve and restore these vitally important animals. As of now, the technology is far from usable. Most experiments have resulted in the death of the cloned embryo. However, a few have
