Cloning Is The Cloning Of Cloning

“Of Wilmut’s nearly 300 attempts to clone a sheep, only 29 reached embryo status and were implanted into ewes; of those 29, Dolly was the only successful pregnancy” (Harris

Unlike some movies, cloning in real life doesn’t produce a full grown exact replica of someone. A type of cloning that occurs naturally is when identical twins are born (“What Is Cloning?”). Somatic cell nuclear transfer (SCNT) is a type of cloning that has to be done in a lab. In SCNT they take the nucleolus out of an egg cell, replace it with the nucleolus of a somatic cell (body cell with two complete sets of chromosomes), and make the egg cell divide into a blastocyst (“What Is Cloning?”).

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

On July 5, 1996, the first animal was cloned. After 277 attempts, the Roslin Institute in Roslin, Scotland successfully cloned Dolly the sheep (Nardo). Dolly the sheep was born by a somatic cell nuclear transfer, or SCNT. The nucleus from a somatic cell of a sheep was injected into an unfertilized egg that was removed of a nucleus.

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.

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

Dolly the sheep, a clone born in Scotland in 1996, was the first mammal to ever be cloned from an adult cell using nuclear transfer. Her birth demonstrated for the first time that even DNA from already specialised adult cells could be used to create an entire healthy organism.

Cloning in its simplest definition is an creating an exact copy of a biological entity, meaning that if 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

On February 24, 1997 history was made. The first cloned adult mammal was born through somatic cell nuclear transfer (McCuen, 11). Somatic cell nuclear transfer is when a nucleus of a mammary gland is removed and fused with an egg by using electrical pulses. The pulses prompt the egg to divide to form an embryo. The embryo is then transferred to a uterus where it is implanted to grow (McCuen, 10). Before the creation of Dolly, many scientists were unsuccessful in their attempts to produce a genetically identical copy of a cell. In the rare occasion that they were successful in their attempts, they would soon be discouraged due to the inability of the clone to sustain life. It took hundreds of attempts before Dolly’s team of scientist could obtain a successfully cloned sheep. Of the 277 successful transfers, only 29 became embryos. And of these 29 embryos, Dolly was the sole survivor (Sweat, 1). What sets Dolly apart from previous clones is the fact that she was cloned differently. Dolly was cloned not from sex cells but from mature mammal cells with no reproductive function (Sweat, 1). Even though Dolly was a

Cloning is defined as the “creation of an exact copy of a living matter, such as a cell or organism” according to Encarta encyclopedia. The copies produced through cloning have identical genetic makeup and are known as clones. Scientists use cloning techniques in the laboratory to create copies of cells or organisms with valuable traits.

Cloning, an ethical issue that has been pressed across the globe, has become a substantial debate throughout a majority of nations. The incorporation of a new type of reproduction in the United States has a plentiful amount of benefits for certain animals and objects, but duplicates of humans is hard to comprehend for many people across America. Currently, cloning is an interesting topic that could become a new way to improve reproduction of animals and humans, prevent diseases, and increase the overall health of Americans.

Cloning and selective breeding have been used to get the desired genetic makeup of animals. Cloning is the process of producing genetically identical copies of organisms that have identical DNA. The copied material is referred to as a clone. Clones can happen naturally such as identical twins Or they can be produce in a lab. A wide range of biological material have been successfully cloned such as cell tissues and even whole organism such as a sheep. In 1996, Dolly the cloned sheep was successfully cloned by Ian Wilmut and his colleagues in Edinburgh Scotland. There is two ways cloning can be done by the somatic nuclear transfer or artificial embryo twinning.
