Cloning is the process of producing individual organisms with identical or virtually identical DNA, either by natural or artificial means. It was discovered as a result of long scientific studies. There are scientific cloning methods that scientists perform using the laboratory environment. Examples of these include gene cloning, reproductive cloning, and therapeutic cloning. Some of the cloning involves the resuscitation of farm animals and dead animals, as well as bringing extinct species back to life, but it is mostly human cloning for reproductive purposes that opposes cloning and leads to bans.
Many scientists are looking for the advantages of cloning in order to conduct a more comprehensive research on cloning despite this, many countries have imposed bans on human cloning. Among the advantages of cloning are the cloning of organs and tissues needed for surgery (If laboratories can clone and grow only the parts needed, this will eliminate the moral and ethical problems associated with decolonizing an entire person). Other benefits include the production of stem cells, cloning genetically engineered laboratory mice for specific studies, bringing back extinct species, reproducing a decayed animal, and cloning animals for food.
One of the main disadvantages of cloning is that the gene defects that the original organism had are passed on to the cloned organism. the first sheep cloned in 1996, Dolly, was a genetic copy of a six-year-old sheep. Dolly only lived to be six years old. This period was the lowest of the average life expectancy of a sheep. By the age of five, he developed arthritis, and at the age of six, his life was ended due to tumors in his lungs that were found in the genome of the original.
No matter how dangerous cloning is, it is an important invention for humanity. Thanks to cloning, we can avoid many problems that will occur in the future. For this reason, more research should be done on cloning with the measures taken.
