cloning Essay -- essays research papers

Cloning Can cloning be beneficial to us? Or is cloning a waste of time and dollars? Cloning as of recent years, has become a very controversial issue. Society is firmly divided on the uses and ethics of cloning. Cloning can range from copies of plants and animals to clones of humans and human organs. Should we clone humans and human organs? Why clone human embryos? There are many legitimate reasons for investigating cloning. Embryologists believe that the research could help improve the lives of further generations. "Cancer research is possibly the most important reason for embryo cloning. Oncologists believe that embryonic study will advance the understanding of rapid growth of cancer cells. Cancer cells develop at approximately the same phenomenal rate as the embryonic cells do. By studying the embryonic cell growth, scientist may be able to determine how to stop it, and also stop cancer growth in return." Another use for cloning is growing organs and / or tissues for humans. Cells can be manipulated to revert their embryonic stage and then these cells will have potential to grow into other tissues, cells, etc. This is done through chemical signals called fibroblast growth factors. These signals "tell" the cells what to do. These same chemical signals are also used on embryos. The fibroblast growth factors tell the cells what to become. Hans Spemann found the organizer effect, which is how the embryonic cells are aligned... cloning Essay -- essays research papers Cloning Can cloning be beneficial to us?
