Hello, today I will be telling you about cloning as well as the pros and cons of cloning. History:Cloning first started in 1902, when a German scientist Hans Spemann split a salamander embryo in two. Each half grew into a separate adult salamander. Spemann proved that cells keep their genetic information even when they are divided. Then, in 1928, Spemann took a nucleus from one salamander embryo and placed it in the egg of another salamander. The nucleus developed into a cloned salamander, and the nuclear transfer cloning process was created. Following Spemann’s discoveries, two American scientists, Robert Biggs and Thomas King, transferred cells from frog embryos to create tadpole clones in 1952. Pros: The pros of cloning animals are that it will lower the risk of animals getting extinct or being endangered. It also will help us get a higher resource such as if we clone sheep’s we will get more fur if we clone cows then Milk, Cheese, and meat. Many doctors recommend that cloning to be used to replace failing organs. This will kill the waiting list for people to get organs delivered for the replacement of their organ such as if their lungs were all black because of smoking. With cloning, organisms can be customized to suit the needs of whatever research purposes being done. Using genetic alteration in plants and animals, researchers can make cloned organisms needed for research instead of hurting animals that are not clones. Organisms that are difficult or slow inbreeding cloning will help it breed faster. Some plants do not produce seeds so cloning will help us make seeds. All the new plants are genetically identical they will all have the desired characteristics. Pigs may be able to grow replacement organs for use in human transplant surgery. You can also use cloning to help humans by cloning pigs. The pigs would first have human genes inserted into their cells so that the organs would not be rejected when transplanted into a human. Inserting human genes into a pig is an extremely difficult job. Once it has been done successfully the pig would be cloned so that many copies of the organ could be grown. Cons: The cons of cloning animals are that 95% of animal cloning has ended in failure due to genetic defects, and cloning is considered unsafe because of it. The idea behind cloning is to harvest cells from a donor, raise them to the embryonic stage in a petri dish, and then place them in a surrogate to grow to term. However, there is a high possibility that the age of the donor will be imprinted on the growing embryo instead of a baby born in the natural way of life. This would cause premature aging issues and potentially lead to premature death. Imagine discovering that you are the clone of a child your parents lost, and you live your life always being compared to the dead child you would then learn that you are a foster and have none to support you in your life how would you feel. Animals do have feelings and what do you think animals would want to be properly born or made in a petri dish in a lab not in the wild or at least a farm.Cloning humans is a dangerous proposition; most attempts to clone other mammals have failed. If women tried to carry eggs containing cloned embryos to term, they would be subject to psychological and physical risk. Moreover, among those mammals that are successfully cloned, there are high rates of deformity and premature death. My opinion on cloning:My opinion on cloning is that cloning can be used to clone animals if they are close to extinction. It is good in a way to help humanity but could going against nature make things worse or better? How cloning is part of nature:Some organisms in nature such as aspen trees reproduce by cloning, Sea Sponges, Tapeworms, Aphids, Jellyfish, Marmorkrebs, Boa Constrictors, Whiptail Lizards, Gall Wasps, Komodo Dragons and Hammerhead Sharks do to also. After conducting tests on some young male Komodo dragons, it was confirmed that the babies were not an exact genetic match with the mother. Instead of a male and a female DNA be jointed, instead, the mother’s DNA was apparently multiplied by two to create the young and showed no presence of male DNA in their genes. What is Cloning: Cloning is a creation of an organism that is a meticulous copy of another. This also means that every solitary piece of DNA is identical connect the two. Cloning is when an organism is made not in a natural way but using a cell from an organism and the DNA is taken out and put into an oocyte, that has had its own DNA-containing nucleus removed. Then the egg has the clone inside being produced in a natural way. When the egg is fully formed to a regular size egg it is put into the womb of an organism and then is born. Conclusion:Today I told you about; The history of cloning, Pros & Cons of cloning, My opinion on cloning, How cloning is part of nature & what is cloning.
