Cloning In A Nutshell
The era of cloning
Scientists have successfully made the most anticipated breakthrough in the field of human cloning by developing skin cells into early-stage embryos and exploited to create specialized tissue cells for transplant procedures. Human cloning is the formation of a genetically equal and identical copy of an existing or earlier existing human being cloned tissue from that individual. Moreover, the term is referred to artificial human clones in the form of identical twins during the process of reproduction. However, genetically identical does not mean purely identical, although genes are said to have recognized as influencing conducts and cognition. These are different people with different experiences and unlike personalities despite being natural human clones.
What is cloning?
Cloning describes a process used to produce genetically identical replicas of a certain biological identity. Usually, when hearing the word cloning, one immediately thinks of artificial cloning of an entire animal even though these processes occurs naturally in some bacteria or plants. For an animal/ human being cloned, scientists take out a mature somatic cell from the natural animal that is being copied. Then the preferred DNA is transferred to the same species from which the DNA was removed and injecting it into the egg of the animal. Moreover, the egg that was cloned is permitted to establish into an early embryonic phase before it is injected back into the womb of a fully developed female for gestation.
Cloning is also a significant practice in another aspect of science, although slightly differing from reproductive cloning. For an instant, therapeutic cloning, that is the replication of embryonic stem cells for testing and creating damaged tissues rather than cloning a whole being.
Cloning humans to the extinct of possibility is still on the way, considering that there are no such records of a fully developed human being cloned. The nearest tests and discoveries the scientists came across was the cloning in 1997, that of a monkey. However, successful human clone embryos were experimented and created from both the adults as well as the infants but did not allow them to fully mature.
Despite, the advancement in technology making the scientist able to clone humans, it is unlikely to proceed further for its ethical reasons such as the occurrence of highly failed rates generating poor health and abnormally large organs and die at the very early stage. It is prohibited in some states to completely clone but in some it is permitted to clone an embryo but banning it to fully mature. For these legal and ethical reasons, the future of therapeutic cloning will be preferable rather than reproductive cloning to develop ways to cure patients and diseases.
