A clone is a genetic replica of organisms formed from a single common predecessor. The first cloning occurred in 1964 by John Gurdon, an English biologist. He acquired it from the abdominal cell nuclei of toad tadpoles and infused them into unfertilized enucleated eggs. An enucleated egg is one from which the nucleus has been detached or demolished. John Gurdon discovered that when the eggs were incubated, some of them became fertile, fully grown toads. Cloning can also be used on plants. Cloning should be allowed for its medical and agricultural benefits and the possibility of helping endangered animals. First of all, cloning should be allowed for its many medical benefits. In the field of medical care, scientists are starting to use genetic cloning to create vaccines and hormones. To help children, the hormone insulin was produced to treat diabetes and growth hormones. The immune system has many antibodies, and scientists clone specific ones that help fight disease or infection (“Clone and Cloning”). Gene therapy changes the expression of a person's genes toward a therapeutic target as a way to treat diseases (Sampsell). The potential for cloning to alleviate suffering is substantial. It could be used to grow the patient's own cells and tissues to make repairs (Wagner 99). Another way cloning can help in medicine is by helping infertile patients. Two fertility doctors plan to use human cloning to help infertile people who use reproductive cloning. Cloning can be used even if the male in the couple has no viable sperm and the father may still have a genetic relationship with the child (Siedler 70). Reproductive cloning, or somatic nuclear transfer, which is the cloning of human beings, can clone sperm or eggs… middle of the paper… at the speed of the process. Although cloning plants and animals can make them more susceptible to disease, cloning can select for more disease-resistant traits that help crops and animals survive. Choosing stronger genes can help the environment become stronger and more prosperous (Sampsell). Cloning is becoming more and more widespread as more and more scientists become interested in the topic. Some people are against cloning and some support it. Cloning research should be able to continue due to benefits in medicine, such as helping to cure diseases, benefits in agriculture, such as choosing certain preferable traits, and benefits in helping to bring endangered or even extinct animals back to life. Cloning research will have many beneficial effects on future projects. It has great potential for the coming years and for the earth.
