Scientific promising future that cloning claims to

Scientific research is always advancing and leading to new discoveries as the future proceeds and technology becomes more advanced. Cloning is a recent on going research that was first developed in the 1990s. Cloning is the process of producing genetically identical copies of an organism.  Cloning is a controversial topic today that regards different opinions amongst different people. Despite the promising future that cloning claims to sustain, cloning is ethically and morally wrong. The cons of cloning also outweighs the pros. There are three types of cloning: gene cloning, therapeutic cloning, and reproductive cloning. Gene cloning involves a piece of a DNA strand being removed from an organism, and united with a plasmid to reproduce itself to replicate multiple copies of the same DNA code which can then be inserted into a foreign host cell ultimately producing copies of segments or genes of DNA. Therapeutic cloning involves the cloning of embryos to produce embryonic stem cells for cloning working toward creating tissues to replace previously injured or dead tissues. Reproductive cloning is the process in which cell is taken from the organism being cloned, and the DNA from the donor cell is then inserted into to an egg cell whose DNA cell has been previously removed. The egg cell is now activated and begins to divide as it were fertilized, resulting in a embryo. The embroyo is then inserted into a surrogate female organism. The surrogate carries the embryo as an average length of a pregnancy before giving birth to the clone. The clone is a genetic copy of the donor organism from which the original cell was taken. Through research of cloning it has proven to be inadequate. Cloning is highly inefficient in which more than 90% of cloning attempts have failed to produce viable offspring.  (2)  Cloning  is not only highly inefficient but also highly expensive. It is also assumed that cloning can be used to save endangered species, but this would be exceedingly costly. (4) To clone a dog, a common species, it can cost  approximately fifty thousand dollars. If a endangered species was to be cloned it is believed that it would be more expensive because of the rarity of the species. There would also be a shortage of donor cells, and it is not promised that the cloning process would be successful. Of the organisms that have been cloned however they have not lived long enough to generate convient data about how clones age. It is also suspected that cloned organisms age faster because of the possibility that the age of the donor could be imprinted on the growing embryo. (2) Cloned organisms additionally tend to have a more compromised immune function and higher rates of infection, tumor growth, and other disorders. (1) Dolly was the first mammal cloned from adult DNA who was a Finn Dorset sheep. Dolly died at six years old, whereas most Finn Dorset sheep live to be eleven to twelve years old. Dolly also suffered from lung cancer and crippling arthritis which could have been caused due to the cloning. Problems of cloning may additionally result from programming errors in the genetic material from a donor cell. Cloning also interferes with nature. Although people believe that through the application of cloning they can bring back loved ones through the use of their cells, however organisms created using nuclear transfer technology isn’t actually truly an identical clone of the donor because only the clone’s chromosomal or nuclear DNA is identical to the donor. Cloning is also suspected to be able to create children for infertile parents that are genetically related, in spite of the estimated cost for cloning humans is two million dollars. (3) Cloning is still a developing research of the process of genetically identical copies of an organism that . It is a continuous argument about whether it is convenient or unsuitable, but at the end of the day the cons exceed the pros of cloning. Cloning is expensive, highly inefficient, interferes with nature, isn’t truly an identical clone of the donor but only the chromosomal or nuclear DNA is the same, cloned organisms tend to have more disorders and diseases, faster aging, and there is no proven good data about how clones age because no clones haved lived long enough.
