CloningIntroductionFrom as early as the beginning of this century until this present day scientists are looking for safe ways to clone animals and also human beings. This issue of cloning will raise so much controversy; some people feel that it is very wrong and should be banned forever and others feel that cloning is one of mans greatest accomplishments and should be experimented on humans. There are many implications relating to the issue which are all equally important and have to be taken into consideration in discussing them.Cloning is a procedure in where a cell is taken from a male organism and combined with an egg from a donor female. Once they are both taken, they are combined, fertilized, and then placed back into the uterus for incubation. By taking this cell from another organism, you are giving the expected off-spring an exact replica of the subjects DNA. Everyone knows that each organism's DNA is different. This procedure would totally redefine everything technology has worked on for the past one hundred years.Biological and environmental implicationsThere are different opinions held which consider both biological and environmental implications towards the issue. Both sides, the advantages and disadvantages are strongly accepted and balanced with respect to the evidence that is known to us recently.By cloning humans it would be better for scientists to understand the human genome and for further understanding our past. Another reason for cloning humans is that there is a very long organ transplant waiting lists and if you were to clone humans and harvest their embryos those people on the waiting lists lives would be saved and the waiting list would be no more. This might solve a lot of our problems and answer a lot of questions.Cloning might also directly offer a way of curing diseases or a technique that could extend means to acquiring new data for the sciences of embryology and how organisms develop as a whole over time, but it will not only erase our individuality, which is almost bad enough in it, but also it will also eliminate the bad genes, and lead to dangerous narrowing of diversity in the gene pool. It means that if everyone is cloned over and over again off the same genes, there is a bigger chance of a mutated gene being prominent and then there would be no way to get rid of it. This is the main reason that science is reluctant to clone humans. So when there is a decline in genetic diversity and the gene pool we lose the ability to clone, scientists will resort to a process known as inbreeding, where it also increase the chance of mutated genes. But in the contrary, if natural reproduction were to occur, genetic variation would occur.Currently, the agricultural industry demands nuclear transfer (the making of an embryo that will develop into an identical twin) to produce better livestock. Cloning could massively improve the agricultural industry as the technique of nuclear transfer improves. Currently, change in the...

Cloning Essay

702 words - 3 pages Cloning In recent years, the issue of cloning has been up for debate worldwide. Cloning is the production of one or more individual plants or animals that are genetically identical to another plant or animal. There are two different types of cloning procedures, embryo cloning and adult DNA cloning. Embryo cloning occurs when sperm and egg cells are mixed in a glass dish.
