Some have suggested that the “fear of the unknown” aspect of cloning mammals, though understandable, is largely unfounded. The potential benefits are numerous and outweigh the concerns brought forth by those who don’t fully understand the process or implications of cloning. Laws and regulations related to this new science will be implemented to address the ethical implications but it’s impossible to stop scientific exploration. The birth of Dolly the sheep represents the birth of a new, exciting scientific method that will change the course of medical history for the better.
The Scottish scientist Ian Wilmut of the Roslin Institute, along with his colleagues, announced on February 23, 1996 they had cloned a sheep by using a ground-technique. The method involved transplanting genetic matter from an adult sheep into a hollowed-out egg, an egg that had its nucleus removed. “The researchers fused the adult udder cell with an (egg) that was ready to be fertilized, but taken from a different sheep. The scientists had previously removed the nucleus from the (egg) using an electrical current to fuse it with the udder cell.” (Barnes, 2012). This sequence instigated cell division. The resulting embryo was then implanted into another sheep who acted as the surrogate-mother. The secret to this method’s success was making the nucleus of the donor’s udder cell “silent” so it would quit performing as it was originally intended and then reprogrammed it to act as an embryonic cell. That embryo would become Dolly; a sheep with three “mothers” involved but only related biologically to the one that donated an udder cell. Dolly shared all of the udder donor’s chromosomes but none of the host egg cell’s chromosomes. Consequently, Dolly is an exact genetic reproduction of the donor-cell sheep.

Cloning is a scientific research which has been central to many debates and arguments. Cloning is a process through which identical organisms are created. This is achieved through asexual reproduction in which only one parent is involved and no fusion of gametes occurs.
As it has been developed and explored, numerous conceptions have emerged regarding the relative benefits or limitations of a broad movement toward a 'created' future. In recent years, the ability to create humans has moved from the graveyards of the Victorian era to the petry dishes of modern laboratories, but the concept and the drive to build a stronger, better man continues in the form of cloning.
The author states that cloning is discouraged by various nations as cloning is against the rule of nature, which is generating humans, nurturing them and paving the way for uncertainties related with the repercussions of science. At present human population has crossed the figure of 7 billion, a huge burden on the planet.
These duplicates are then provided with favorable growth media and other conditions to proliferate. Initially, only cells were being cloned; but with the course of scientific development the scientists’ progressed unto cloning groups of cells which could be used to develop complete organs or tissues.
The technological advancement proved by the existence of Dolly represented major medical progress, a new method for curing illness. The event also caused great apprehension from those worried it may mean a future populated by human clones. The questions concerning human cloning have been a troubling topic of throughout all segments of society
The scientific term, “Cloning” is the replication of an organism such that its genetic makeup is the same and as a result,it appears as a carbon copy of its original counterpart. Clones have the same physiology, external appearance and the same genetic coding within their cells.
This procedure results in creating the embryonic growth of a new organism which contains the original organism’s entire genetic code. Hundreds of cloned mammals have resulted by means of this process. “The term clone is used in many
Though the issue of cloning human beings has received criticisms from different sectors of society, it can be observed that some people advocate for this process as a result of different reasons. For instance, parents
