ART (REPRODUCTIVE CLONING)

I did my research on cloning. This topic interests me because it's controversial.

-The following site: http://www.ornl.gov/sci/techresources/Human_Genome/elsi/cloning.shtml defines cloning as:

-Reproductive cloning is a technology used to generate an animal that has the same nuclear DNA as another currently or previously existing animal.

-The success of Dolly's cloning proved cloning to be accurate in transfering genetics to develop an entirely new organism.

-Some scientists believe that errors or incompleteness in the reprogramming process cause the high rates of death, deformity, and disability observed among animal clones.

-Reproductive cloning is expensive and highly inefficient. More than 90% of cloning attempts fail to produce viable offspring.

-In addition to low success rates, cloned animals tend to have more compromised immune function and higher rates of infection, tumor growth, and other disorders.

-The cost of cloning may be around $100,000 a treatment.

Physicians from the American Medical Association and scientists with the American Association for the Advancement of Science have issued formal public statements advising against human reproductive cloning. Currently, the U.S. Congress is considering the passage of legislation that could ban human cloning.

Wikipedia gave a more simple definition:
Cloning is the process of creating an identical copy of something.

Do you approve of human cell cloning for research?

“For research, yes, because I think you can do it in an ethical way that helps all mankind without being too immoral.”
— Jon Lomshek, consulting, Kansas City, Kan.
“Sure. I just think it can lead toward advancements in disease treatment.”
— John Hay, dentist, Lawrence
“No. I just don’t think it’s right. It’s immoral.”
— Larry Williams, construction worker, Topeka
“No. People shouldn’t have the right to do that.”
— Amelie Gras, student, Lawrence

By using yahoo search, I came across similar websites. The yahoo search panel gave me more options as to specific kinds of reproductive topics.

http://www.yahoo.com/

Research methods:
Broad or general terms will return thousands of possible sites. Try to use terms that are more specific to your topic.

Boolean Operators are words that allow you to combine search terms.
For example:

AND

AND tells the search engine to find both terms on the same site. For instance, entering "reproductive AND cloning" would instruct the search engine to find web pages that contain both words, "reproductive" and "cloning."

OR

OR instructs the search engine to find one term or the other. Entering "reproductive OR cloning" would cause the search engine to look for web pages that contain either the word "reproductive" or the word "cloning," but not necessarily both words. This option could return a thousand sites because it isn't specific.

*If you want your search engine to search for an exact phrase, put quotation marks around the phrase.

To have easy access to websites previously viewed, you should bookmark it.
