Reproductive Cloning

I think that once there is a successful procedure done there will initially be a very small market for human

The topic of cloning has brought much debate in science and also in society. Many

Human reproductive cloning is a type of cloning that involves somatic cell nuclear transfer and the embryo duplicates the genome of solely one parent, a type of asexual reproduction that is foreign to the human species. This form of reproduction differs from normal sexual reproduction where the baby duplicates genomes of both parents (Hayry 2003). Despite popular beliefs that view reproductive cloning as a carbon copy of human beings, in actuality it creates a genetically and physically identical twin of its progenitor but socially and psychologically it reproduces an unique human being (Morales 2009).

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.

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

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

Cloning is a complicated process of creating cells from things other than a sperm and egg cell. There are three basic types of cloning. Gene cloning is the simplest and makes exact copies of segments of DNA. Reproductive cloning, the kind used with Dolly, is when a whole animal is reproduced. Therapeutic cloning is the creation of cells and tissues that are intended to be used for experiments or replacing diseased

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.

The SCNT, which is the cloning process occurs as follows: The scientists take a normal cell (for example a skin cell) from the animal’s body, and receive from it the genetic material (DNA). This DNA transferred into a cell egg, evolving to

“Clones are organisms that are exact genetic copies. Every single bit of their DNA is identical” (Cloning). Clones can range anywhere from clones of whole organisms to clones of cells. “There are two ways to make an exact genetic copy of an organism in a lab: artificial embryo twinning and somatic cell nuclear transfer” (Cloning). Artificial embryo twinning is the “low-tech” way to create clones (Cloning). Artificial embryo twinning mimics the process in nature that creates identical twins (Cloning). In nature, twins in the first days after the egg and sperm join (Cloning). The embryo at this point is still made of a small number of unspecialized cells (Cloning). Identical twins are genetically identical because they are developed from the same fertilized egg after the embryo splits in half (Cloning). “Artificial embryo twinning uses the same approach, but it is carried out in a Petri dish instead of inside

There are a few ways in which cloning can be achieved, one of which is somatic cell nuclear transfer, SCNT. SCNT has become the most practical way of reproductive cloning. Although the success of somatic cell nuclear transfer is very low, 0.1% - 0.5%, the few successes in cloning have been with the use of SCNT. Somatic cell nuclear transfer is a technique that transfers the nucleus of a cell into the cytoplasm of another cell which has no nucleus. Once inside the egg, the nucleus is reprogrammed by egg cytoplasmic factors to become zygote nucleus, a fertilized egg. Since the nucleus holds all the DNA, or the directions for life, the cell will proceed to grow into the organism of which the nucleus came from. Scientists needs more than just a method of cloning to bring back an extinct species. They need an intact DNA strand, and the longer a species has been

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

of the work with clones is done from cultures. An embryo has about thirty or

Essay Question (2): Explain in full the ‘life in the shadow’ argument against human reproductive cloning. How might the argument be objected to? Do you regard the argument to be morally decisive, in the sense that it establishes that human cloning for purely reproductive purposes must never be permitted? Explain and defend your answer.
