An Ethical Dilemma/ Stem Cell And Cloning

An Ethical Dilemma: Cloning/ Stem cell Research What is stem cell research and cloning? If you were to sit down and reminisce upon your childhood memories, I am almost 100% sure that clay would be running around in circles in your head because as a child you ran around in circles with clay thrilled about your new handmade creation. Nevertheless, clay would be prominent upon your childhood memories because no matter what your economical status was you were able to shape it using your God-given creativity and make it into whatever your heart desired. In addition, there was no limit to the amount of creations you could make because clay was inexhaustible and never-ending. The ...view middle of the document...

In some adult tissues, such as bone marrow, muscle, and brain, discrete populations of adult stem cells generate replacements for cells that are lost through normal wear and tear, injury, or disease.When the media accounts on cloning in the news, they are typically speaking about only one type called reproductive cloning. There are diverse types of cloning however, and cloning technologies can be used for other purposes besides producing the genetic twin of another organism. The terms "recombinant DNA technology," "DNA cloning," "molecular cloning," or "gene cloning" all refer to the same process: the transfer of a DNA fragment of interest from one organism to a self-replicating genetic element such as a bacterial plasmid. The DNA of interest can then be spread in a foreign host cell. This technology has been around since the 1970s, and it has become a common practice in molecular biology labs today. Reproductive cloning is a technology used to generate an animal that has the same nuclear DNA as another currently or previously existing animal. Dolly was created by reproductive cloning technology. In a process called "somatic cell nuclear transfer" (SCNT), scientists relocate genetic material from the nucleus of a donor adult cell to an egg whose nucleus, and thus its genetic material, has been removed. The reconstructed egg containing the DNA from a donor cell must be treated with chemicals or electric current in order to kindle cell division. Once the cloned embryo reaches a appropriate stage, it is transferred to the uterus of a female host where it continues to develop until birth. Therapeutic cloning, also called "embryo cloning," is the production of human embryos for use in research. The objective of this process is not to create cloned human beings, but rather to produce stem cells that can be used to study human maturity and development and to treat ailments. Research Christopher Reeve. Explain what happened and why? Why did he campaign for stem cell research?Superman actor Christopher Reeve, who turned personal tragedy into a public crusade and from his wheelchair became the nation's most recognizable spokesman for spinal cord research, died October 10, 2004 of heart failure. He was 52 years old. Reeve is survived by his mother Barbara Johnson and his father Franklin Reeve, his brother Benjamin Reeve, his wife Dana, their twelve year old son Will and his two children from a former relationship, Matthew (25) and Alexandra (21). Reeve died of complications from an infection caused by a bedsore. He went into cardiac arrest Saturday, while at his Pound Ridge home, then fell into a coma and died Sunday at a hospital surrounded by his family, his publicist said. His advocacy for stem cell research helped it emerge as a major campaign issue between President Bush and Sen. John Kerry. His name was even mentioned by Kerry during the second presidential debate on Friday. In the last week Reeve had developed a serious systemic infection, a...

Whilst Buddhism may have lost its power in later years, the establishment of this religious movement provoked an exaggerated response from society.Modern age questions why the transition of Buddhism was accepted so readily within its original context. Whilst the historian cannot report all the reasons this occurred, a definitive principle is essentially contained within the moral and ethical values of the historical figure 'The Buddha'. His moral activity and philosophy affected a mass response from the context of his time and, as a result, within modern society as well.

The stem cell alternatives such as adult, placenta, and umbilical cells do not raise any ethical issues.      The research of stem of stem cells is important. From all three stem cells (embryonic, adult, and umbilical cord) we hope to find cures for: diabetes and brain diseases such as Parkinsons. These

The central concept of stem cell research is the stem cell’s unique ability to reproduce for an indefinite amount of time and its ability to differentiate into any type of cell in the body, such as a muscle cell or a liver cell. This is unlike normal cells in the body, which can divide for only specific amounts of time and remain a single cell type, for example, a muscle cell remains a muscle cell and

This Essay Is How To Clone

1289 words - 6 pages Since the late seventies scientists have been cloning mammals using cells taken from embryos. In July 1996, medical history was made when a sheep named Dolly was cloned. The only thing that set Dolly the sheep apart from the other clones was that she was cloned from an adult sheep cell. Before Dolly was cloned, scientists thought adult cell cloning was impossible. A clone is defined as a group of genetically identical cells. The goals and

Pros and Cons of Cloning

564 words - 3 pages breed individuals with certain traits. Probably the most contentious issue in the debate about the pros and cons of cloning is the ethical side of the process. Is it ethical to act like God by creating an embryo that develops into a human being? Is it ethical to kill a pre-embryo in order to harvest its stem cells, which will then be cultivated into an organ for transplant purposes? Is it ethical to mess around with nature in the first place? Indeed, if you must take sides in the pros and cons of cloning debate, your main responsibility is to enter it with an open, educated and informed mind first and stable emotions second.
