Amongst the rapidly growing field of genetics lies a rather peculiar process which once was the pinnacle of Science Fiction now a certain absolute in reality - Cloning. Regardless of any controversial issues surrounding this process, it is now more widely used than ever and if the facts surrounding the issue are any indication - from a technical aspect, a successful process could prove highly beneficial to the human race. Reminiscent of fictional entities, one may believe cloning to be a process in which a physically similar duplicate of an organism is created sharing key personality traits, and age. Meanwhile, the possibility of being genetically modified to produce desirable traits whether physically or mentally remains a conceivable option. Epitomized, this concept isn’t too distant from the reality of the situation. In stark actuality, cloning is a process/or number of processes in which a genetically identical replicate of a biological entity is created.
Various biological matters can be cloned, from the simplicity of a single cell to the complexity of a multicellular organism such as an animal. Though conceived as minor, it is key to note that cloning a multicellular organism does not result in the duplicate sharing the same age, memories, or necessarily the exact same personalities(though there may be some similarities) as only DNA is shared between the two organisms (original & clone). Cloning, quite evidently is an intricate process though isn’t necessarily always executed through artificial means as it may be found in one of the most significant aspects of nature-Asexual Reproduction. During asexual reproduction, unicellular organisms, such as bacteria allocate in two, resulting in two genetically indistinguishable individuals. Artificial Cloning, can be simplified into three unique types/forms including; gene cloning, reproductive cloning, and therapeutic cloning. Gene cloning results in duplicates of particular sections of DNA or genes. Reproductive cloning which is the most prevailing form of cloning found in fictional pieces produces replicates of entire organisms while Therapeutic Cloning brings about embryonic stem cells for the purposes of experiments/trial runs intended to create biological tissues to replace damaged/and or infected tissues.
The procedure of cloning may be executed through a variety of manners, the particular specifics altering circumstantially such as by basis of the organism and external/environmental variables. Such an example may be found in the undertaking of genetic (gene) cloning. During, this process, the gene of an organism (“foreign DNA”) is interpolated within the genetic matter of a carrier termed a vector which can deviate from simple life forms such as bacteria to organisms with the likes of yeast cells, viruses, and even plasmids. Preceding the placement of the gene, the vector is placed in a location with conditions similar to that of a laboratory, stimulating it to multiply/duplicate itself numerous times. More complex organisms such as animals may be cloned through the manner of extracting a somatic cell (which can be any cell in the body excluding sperm cells) and placing in it in an egg cell which has had the DNA confined to it removed. The egg containing the somatic cell is then placed in the womb of a female animal pertaining to the same species where it is permitted to grow and eventually, produce an exact genetic duplicate of the original organism.
While ethically questionable in the case of humans, cloning animals can be quite beneficial such as in the case of rats, who are often used in experiments. Cloning these organisms would ensure that results are materially more consistent as the subjects would contain the exact same genetic material as their peers. The insurmountable applications of cloning certainly are not limited to this as each duplicate may be modified to produce/and or contain something which may assist humans in progress in several scientific fields of interest, perhaps most significantly in medical terms. An exemplar of such an occurrence may be found in the modifying of sheep following the precedent that Dolly (first mammal cloned by use of somatic cells) set, to produce milk containing a nutrient essential for blood clotting, therefore providing an essential relief for humans who lack proper blood clotting. Produce from cloned animals, have likewise proven to be just as efficient and healthy/safe as those resulting from the original animals, which goes to further demonstrate the fact that the potential benefits to be reaped from cloning are innumerable.
Quite regrettably, amongst such positives arises a multitude of ethical and controversial concerns associated with all aspects of cloning.
