Introduction

DERRICK OKRAH THE FUTURE OF CLONING Cloning has been going on in the natural world for thousands of years. A clone is simply one living thing made from another, leading to two organisms with the same set of genes. In that sense, identical twins are clones, because they have identical DNA. Sometimes, plants are self-pollinated, producing seeds and eventually more plants with the same genetic code. Techniques have improved rapidly, making it possible to clone cattle, sheep and other farm animals. How could cloning farm animals be of benefit? Cloning farm animals would be of many benefits among them are One of the major reasons to clone a farm animal is that, it reduces the effort and time needed for farmers to do what they have been doing for years that is selecting and propagating the best of the herd. How could cloning benefit medical research? Cloning would be of a much benefit in medical research, example genetically identical laboratory animals (clones) can be used as models for human disease. The most commonly used laboratory animal is the mouse, it reproduces rapidly and its genetics have been well studied, clones in laboratories such as the Mice will likely facilitate the discovery of new treatments for diseases. ...read more.

The new DNA needs to be reprogrammed to behave though it were the DNA of the egg cell, it takes couple of hours to so this. > The Egg cell with the nucleus will need to be stimulated to start cell division (mitosis) in the Petri dish. A drop of the liquid chemical would be added to mimics the cellular events that occur when an egg cell is fertilized by a sperm cell from a male. The cell will start to undergo mitosis this takes couple of hours. > The embryo would then be implanted into the surrogated mother. The embryo would continue to increase in cell number and begins to differentiate its cells into various tissue types. The pregnancy will continue for about 9 months. > A new baby is now born. It would have everything in common to the person being cloned; it would never have anything to do with the surrogated mother. Who might benefit from human cloning and how might it be used? Everyone might benefit from human cloning from my point of view, consider these below. Infertility. With cloning, infertile couples could have children. Despite getting a fair amount of publicity in the news current treatments for infertility, in terms of percentages, are not very successful. ...read more.

Conclusion

* Biomedical Research: Cloning can produce genetically identical laboratory animals which can be used as models for human disease. The most commonly used laboratory animal, the mouse, reproduces rapidly and its genetics have been well studied. Mice have been successfully cloned and will likely facilitate the discovery of new treatments for disease. Jean-Paul Renard, of the National Institute of Agricultural Research in France, is attempting to produce cloned transgenic rabbits to study cardiovascular disease in the hope of finding new treatments. In addition, it provides a model for studying the interaction of nuclear verses mitochondrial genes and for nuclear verses cytoplasmic factors. * Commercial Endeavours: Noting that no live dog clones have yet been reported, the company PerPETuate, Inc. (Connecticut) is freezing tissue from family pets for the future. Researchers have had little success in the steps required to make a dog clone, such as development after nuclear transfer and embryo implantation into the womb. * Treatment for Human Disease: Cells could be harvested from early embryos to provide cell and tissue replacement without the hazards of transplantation rejection. The U.K. government has recently accepted recommendations from its chief medical to permit research using embryos subject to controls, which include a 14-day limit (see the Department of Health website listed below in "learn more"). ...read more.

    It is argued that the environment plays a very big role in developing an individual, and a clone will never be an exact replica of its original. On the contrary, the two organisms (the original and the clone) that may look exactly the same and have certain similar traits will result as two distinguishing individuals with unique characters and personalities.

    To prevent a mass departure of water from the cell, halophiles make up for the high salt in the environment by accumulating compounds like potassium.
