Human Cloning: Somatic Cell Nuclear Transfer

Human cloning is the creation of a genetically identical copy of a human being, human cell, or a human tissue. The history of cloning dates back to the first creation of a clone of a sheep named ‘Dolly’ in 1997 by a Scottish scientist. Dolly was created by a used cloning technique called ‘Somatic cell Nuclear transfer’, which created a genetically twin animal. After the cloning of Dolly, scientists thought that humans could be cloned, as well. The term ‘Human Cloning’ refers to an asexual type of reproduction. Meaning that an embryo is produced not during a male and female natural sexual production, but rather, it is produced in a laboratory, when scientists combine a sperm and an egg together. Cloning works somehow like the natural

The scientists take a cell from a model (could be an animal, plant, or a human) and remove its core, which contains the entire hereditary material and that contains 46 chromosomes. Then, they implant the core that was removed in an empty cell that had its core removed too, and finally, the egg is fertilized and is entirely complete with the 46 chromosomes that it would have had in a natural sexual fertilization process. The only difference is that the 46 chromosomes are from 1 person and not 2, as you are creating a copy of someone. So basically, if someone clones himself, the produced model is not his sister, brother, son, or daughter, but it’s just a new category of humans, which is that person’s clone/copy. Whilst many scientists now consider the process of human, plant, and animal cloning as a huge invention, still, everything has its pros and cons, and human cloning, of course, is not an exception. First, we’ll start by mentioning some of the pros of

Cloning of animals and humans by using Somatic Cell nuclear Transfer technique is simply insignificant. “The success ranges from 0.1 percent to 3 percent, which means that for every 1000 tries, only one to 30 clones are made.” Also, bringing back Dolly’s (the clones sheep) case, we have to consider that it was the lucky sheep that survived from 227 cloning attempts. Another clone failure is a case of a calf that was born with 2 faces, and shortly, it died. Alas, this process would involve hundreds of failed pregnancies just to achieve one single alive cloned baby. But, why do these failures
