Cloning: how it should be done and should it be done?
Description
The book takes closer look at biological cloning, particularly the type involving complex organisms, mammals and humans. Very recent developments are discussed, as well as ethical issues of human cloning, EU regulations and technologies that may achieve cloning. Below are several quotes from the book:
"A fundamental issue before moving ahead with the cloning of complex organisms, such as mammals, however, is why such cloning should be created? That you can do it technically can hardly be reason enough. The following reasons are often cited:
• Increased food production (reproduction of animals with particularly good genes for production of eg meat, milk and eggs), or copying of animals who otherwise are particularly suitable for food production (easily maintained, high disease resistance, etc.).
• To maintain the desired characteristics of the companion and sport animals.
• For medical therapy (for production of biologically active substances, for the production of bodies possible to transplant to the human).
• Experimental animals (identical animals to study the effects of medication, environmental toxins, opera-tions, and the like).
• To study the role of nature versus nurture.
• To study fundamental physiological and genetic context.
• To examine the possibilities and prospects for human cloning."
"Mitochondria has 40 genes, and is a specialized organelle that is considered to be remnants of an amalgamation of the two bacteria in animal life antiquity. Mitochondrial DNA does not replicate in the nucleus, but comes from the egg cell, and multiply thus normally through "somatic cloning "on the female side of the reproduction. This means that when cloning has actually identity only to 30000-40 divided by 30,000, ie 99.87 percent - whether the remaining 0.23% is more or less important to heritage can not be resolved by counting the number of genes."
