eukaryotic organisms (organisms possessing a cell nucleus) such as humans, all the cells that undergo mitosis, such as skin cells and cells lining the gastrointestinal tract, are clones; the only exceptions are gametes (eggs and sperm), which undergo meiosis and genetic recombination.polymerase chain reaction, or PCR, a technique that is used widely in basic biological research.The type of cloning that is the focus of much ethical controversy involves the generation of cloned embryos, particularly those of humans, which are genetically identical to the organisms from which they are derived, and the subsequent use of these embryos for research, therapeutic, or reproductive purposes.

If you had an illness like diabetes, have you ever wondered what it would be like if you did not.
Cloning is the creation of an organism that is an exact genetic copy of another.
While cloning is justifiable in certain circumstances, I would want to make sure other healthcare issues were taken care before donating money to research for cloning....
[tags: Cloning] - Reproductive human cloning is a form of asexual reproduction done in a lab, not by a sperm fertilizing an egg.
The realization that the DNA of somatic cells could be reprogrammed to a pluripotent state significantly impacted research into therapeutic cloning and the development of macaque monkey embryos were cloned by SCNT, but those clones lived only to the blastocyst stage of embryonic development.
It was more than 10 years later, after improvements to SCNT had been made, that scientists announced the live birth of two clones of the ), the first primate clones using the SCNT process.This issue has been a hot topic for the past decade after Dolly the sheep was cloning in Scotland.Dolly was the first cloned mammal, whose very existence created much heat in the general public (Hansen, 2004).Beginning in the 1980s mammals such as somatic cell nuclear transfer (SCNT), represented an extraordinary advance in the science of cloning, because it resulted in the creation of a genetically identical clone of an already grown sheep.It also indicated that it was possible for the DNA in differentiated somatic (body) cells to revert to an undifferentiated embryonic stage, thereby reestablishing pluripotency—the potential of an embryonic cell to grow into any one of the numerous different types of mature body cells that make up a complete organism.Advancements in the field of molecular biology led to the development of techniques that allowed scientists to manipulate cells and to detect chemical markers that signal changes within cells.With the advent of recombinant DNA technology in the 1970s, it became possible for scientists to create transgenic clones—clones with genomes containing pieces of DNA from other organisms.The first successful clone was in 1997 when scientist Edinburgh cloned Dolly the sheep.She was the first animal to be cloned with an adult somatic cell by using the process of nuclear transfer.Many people believe that cloning is ethically immoral and should never be done, but others think that scientific advances can greatly cure diseases.[tags: Cloning] - Cloning is defined as the different processes for duplicating biological materials such as tissues and new life forms (“Cloning Fact Sheet” 2009).
