Clone
A clone is an organism, or group of organisms derived from another organism by an asexual (nonsexual) reproductive process. A group of cells stemming from a single cell is also called a clone. Usually the members of a clone are identical in their inherited characteristics. An example of clone is identical twins, which originate from the division of a single fertilized egg. Simple organism such as protozoa's, many other algae and some yeast are also reproducing primarily by cloning.Through recent advances in genetic engineering, scientists can isolate an individual gene (or group of genes) from one organism and grow it in another organism belonging to a different species. The species chosen as a recipient is usually one that can reproduce asexually, such as a bacterium or yeast. Thus, it is able to produce a clone of organisms, or cells, that all contain the same foreign gene or genes. Because bacteria, yeasts, and other cultured cells multiply rapidly, these methods make possible the production of many copies of a particular gene. The copies can then be isolated and used for study (for example, to investigate the chemical nature and structure of the gene) or for medical and commercial purposes (for example, to make large quantit
After successful achievements in animal and plant cloning, scientist turns their attention to clone humans. However, there are too conflicts, weather they should clone humans or not. Anti-clones believe Man should not meddle in God's business of creating new beings. They take from the Bible this quote which supports their beliefs "For I testify unto every man that heareth the words of the prophecy of this book, if any man shall add unto these things, God shall add unto him the plagues that are written in this book: And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book." They believe cloning devalues people by depriving them of their uniqueness and that a ban should be implemented upon it. In addition, another problem with asexual reproduction is that genetic diversity becomes limited. If a population of organisms has the same genetic information, then the disease would wipe out the population. This is because not one organism has an advantage of fighting the disease over the other. The technique of nuclear transfer is also early in its developmental stages. Thus, errors are occurring when scientists carry out the procedure. A whole nucleus, containing an entire set of chromosomes, can be taken from a cell and injected into a fertilized egg whose own nucleus has been removed. The division of the egg brings about the division of the nucleus, and the descendant nuclei in turn, be injected into eggs. After several such transfers, the nuclei may be capable of directing the development of the eggs into complete new organisms genetically identical to the organism from which the original nucleus was taken. This cloning technique is in theory capable of producing large numbers of genetically identical individuals. Experiments using this technique have been successfully carried out with frogs and mice. Cloning has become a very important issue that is affecting our world. Even if cloning is limited to medical research, there still will be the risk of cloning humans. We simply cannot play God and create life because it is morall
