Vitro Fertilization Successfully Cloned
1,319 wordsYou have been told that you are unique. The belief that there is no one else like you in the whole world has made you feel special and proud. In the near future, this belief may not be true. The world was stunned by the news in the summer of 1995, when a British embryologist named Ian Wilmut, and his research team, successfully cloned Dolly the sheep using the technique of nuclear transfer. Replacing the DNA of one sheep's egg with the DNA of another sheep's udder created Dolly. Plants and lower...

Human Cloning Controversial Issues
1,772 wordsIn the article that I chose there are two opposing viewpoints on the issue of "Should Human Cloning Ever Be Permitted?" John A. Robertson is an attorney who argues that there are many potential benefits of cloning and that a ban on privately funded cloning research is unjustified and that this type of research should only be regulated. On the flip side of this issue Attorney and medical ethicist George J. Annas argues that cloning devalues people by depriving them of their uniqueness and that a ...

Biology Research In Vitro Fertilization
2,054 wordsIn Vitro Fertilization (IVF), is the procedure whereby human babies are conceived, not in the womb but in a test tube or a Petri dish. This procedure has become one of the greatest developments in the world of medical technology. In Vitro Fertilization has given infertile couples the chance to conceive and bear a child from a full term of pregnancy. Without this procedure, their infertility would render them childless. There are many aspects of the IVF program that have been both praised and cri...

Human Embryo Cloning Human Cloning Foundation
1,890 wordsThe announcement of the cloned ewe, Dolly, in 1997 by scientists in Scotland, was a shock to the entire world. The idea of cloning wasnt new, but at the time still seemed farfetched to most. As John Greeney stated We had not, as a species, ever truly considered the likelihood that human reproduction would fall so fully under the hand of technology (1). However, once the reality of this controversial practice set in, scholars and common people alike began to debate the pros and cons of cloning fr...

The laws may be changed to allow abortions completely, or to forbid them completely. Stem cells will definitely play a part in this decision. It is possible that the action of using fetuses to save lives can make abortions seem less evil. To terminate one life to save others is a decision that the world must make, and not make lightly....

The advantages of these cell cultures soon came into perspective, medical research could soar from this. Certain difficulties were soon overcome and a serum free media wa...
