Reproductive and Therapeutic Cloning: Dolly The Sheep

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.

Therapeutic cloning is a process in which the cells of one person are manipulated into becoming the stem cells for another person through Somatic Cell Nuclear Transfer (SCNT). This process involves taking oocytes, or immature female egg cells that are generated during ovulation, incubating them in in vivo culture, and extracting the nucleus of such cells and replacing them with the the nucleus of another cell. This produces a stem cell with a genetic make-up

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.

Clones are organisms that are exact genetic copies. Cloning originally started in the year of 1885, when a German scientist named Hans Adolf Eduard Driesch began researching reproduction. The process of producing a clone began a hundred years ago. There’s many different types of clones such as, natural clones, molecular clones, organism clones and even therapeutic clones. The first organism cloned was a salamander created by Hans Adolf. Years later, Robert Briggs and Thomas Joseph King clones a frog. Then, there was a famous organism cloned by the of name Dolly, who was the first animal sheep cloned. In order to understand the creation of life one must

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

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

There are two methods of cloning: embryo splitting and nuclear transfer. Embryo splitting involves egg cells being removed from the female donor, which are then fertilised in a laboratory with sperm from a male by

As for reproductive cloning the entire genetic code is reproduced from a single body cell of an adult individual. The most common technique is somatic cell nuclear transfer (SCNT). Scientist first take the somatic cell from the test subject they plan to clone, extract the cell’s nucleus, which includes the cell’s DNA and throw away the rest. Then they remove the nucleus of an egg cell and replace it with the somatic cell. After that step is complete they reconstruct the egg with a blast of electricity to simulate cell division. If the process is done correctly the cell then divides normally and forms a blastocyst, therefore, scientist will transfer it into a foster mother for her to flourish a new animal.

There are two main types of cloning that are known about, therapeutic cloning and reproductive cloning. Therapeutic cloning is when you take a small sample of DNA and insert into an embryo to make the embryo to have healthy parts. The parts are accepted by our body because they are from your DNA. Therapeutic cloning does not happen naturally in nature and it is asexual. Reproductive cloning is another type of cloning and unlike therapeutic cloning is sometimes occurs in nature. An example of natural reproductive cloning is meiosis and plants. This is asexual as well since it is an exact replica of DNA from one sample. Cloning may have many benefits but it has downsides. Cloning is a crude science that should not be researched upon because of its

Have you ever wondered what it would be like to have a second you? The process of cloning is something that is not necessarily very new but is something that is constantly being researched and improved. Most commonly in cloning the somatic cell nuclear transfer method is used.This is when you take a somatic cell(any cell other than the sex cells) from the person being cloned and a donor egg cell and extract the nucleus from the donor egg cell replacing it with the nucleus from the somatic cell. This fuses the donor egg and somatic cell together and next is placed in a surrogate organism that gives birth to that cell that was created. That is the process of cloning an organism. The world of cloning is new and mysterious but is something that could very

The remaining processes of cloning, reproductive and therapeutic, begin similarly through a process called nuclear transplantation. Nuclear transplantation involves removing a nucleus of an egg cell, and replacing it with a different nucleus often from an adult body cell. The

Clones are organisms that are exact genetic copies, and every single bit of their DNA is identical. Identical twins are one of the many examples of natural clones. But as well as babies can be born naturally identical, they can also be created inside a laboratory. But not only new human beings can be created, also new tissues can be created to replace damage tissues. Cloning is a good source because it gives infertile couples the opportunity to have a biological baby, and it gives doctors the opportunity to replace its

Cloning is the process of making an identical copy of any living thing such as gene, cell, or a whole organism. The varieties of cloning are gene, reproductive and therapeutic. Gene cloning is the process in which a gene of interest is located and copied out of DNA extracted from an organism. Reproductive cloning involves creating an animal that is genetically identical to a donor animal through somatic cell nuclear transfer. The A procedure in which damaged tissues or organs are repaired or replaced with genetically identical cells that originate from undifferentiated stem cells, basically it involves creating copies of cells to make someone better. Cloning used to be something that was only in science fiction

There are many different forms of cloning. There is cloning in nature which helps with farming and has been around for thousands of year. The cloning of animals and humans is another form. The first cloned animals were created by Hans Driesch in the late 1800's. His goal was to prove that genetic material is not lost during cell division. While testing sea-urchins, the results ended up with two identical sea urchins. There were no major advances in cloning until November of 1951, when Robert Briggs cloned a frog embryo. We now have the technological advancements to clone a human being.
