That, in a nutshell, was the plot of the high- dollarlow-attendance sci-fi movie, "The Island. In an appropriate Orwellian twist, doctors must murder the "spare" clones in order to harvest needed body parts. Chances are, "The Island" isn't a glimpse into the future.
How it is done; possible benefits Sponsored link. It is fundamentally different from human reproductive cloning; it produces stem cells, not babies. I am thinking in particular of attempts at human cloning with a view to obtaining organs for transplants: Three very different procedures have been referred to as "cloning.
Adult DNA cloning a. Then, the embryo would be implanted in a woman's womb and be allowed to develop in to a new human whose DNA is identical to that of the original individual.
This method has been used to clone a sheep. Adult DNA cloning cannot ethically be used to produce a human clone, because experiments on animals have sometimes produced defective specimens. Somatic cell nuclear transfer or research cloning: This starts with the same procedure as is used in adult DNA cloning.
The resultant embryo would be allowed to grow for perhaps 14 days.
It's stem cells would then be extracted and encouraged to grow into a piece of human tissue or a complete human organ for transplant.
The end result would not be a human being; it would be a replacement organ, or piece of nerve tissue, or quantity of skin. Unfortunately, although adult DNA cloning and therapeutic cloning are quite different procedures leading to very different goals, both terms contain the word "cloning.
Many transfer their disgust at the concept of creating cloned babies to therapeutic cloning whose goal is to create an organ to heal people. Orrin Hatch R-UTa pro-life senator has suggested the term "somatic cell nuclear transfer" to replace therapeutic cloning.
I once had a Swedish ivy plant, and about a dozen empty flower pots. I cut off many leaves from the original plant, placed each of them in a pot filled with damp soil, and surrounded the pots with clear plastic. In a few weeks, I had a dozen new plants. This shows that all of the material and information needed to create a Swedish ivy plant is contained in a single leaf.
Actually, it is contained in a single cell of a single leaf. So too, all the information needed to create a new human being is contained in each cell of an existing human being. DNA testing on an human often starts by scraping some cells from the inside of a person's mouth.
Living cells can be scraped off of a person's skin. No matter how a cell is obtained, it contains the DNA of the person, and thus contains all of the information required to produce a duplicate or cloned person.
Each cell is, in fact, a form of human life for the simple reason that it contains human DNA. A woman's ovum also contains her DNA. What is involved in somatic cell nuclear transfer is to: Take a woman's ovum, and remove its DNA. This converts it to a form of human life into what is basically a factory for creating a pre-embryo.
Remove the DNA from a cell taken from a human, and inserting it into the ovum. Giving the resulting ovum an electrical shock to start up its embryo making operation.
In a small percentage of cases, a pre-embryo will be formed.
Therapeutic cloning, which is also known as organ cloning, is the process of creating new human organs and tissues, never newborn babies, from the cultivation of stem cells. Nevertheless, it brings up a relevant point about the potential uses for human reproductive cloning. Organ transplants are difficult undertakings for two major reasons. First, you have to find a donor, and second, there's no guarantee that your body will accept the new organ. With over , people on the organ transplantation lists in the United States alone, many people need a new organ in order to have a fresh start at life. Some organs can come from live donations, such as a kidney, but others require a tragic death to occur. By evaluating the pros and cons of.
The pre-embryo is allowed to develop and produce many stem cells. So far, the procedure is identical to that used in adult DNA cloning. However, the pre-embryo is not implanted in a woman's womb in order to try to produce a pregnancy.
Stem cells are removed from the pre-embryo; this results in its death.
The stem cells would be encouraged to grow into whatever tissue or organ is needed to treat the patient. Stem cells are a unique form of human cell that can theoretically develop into many organs or body parts the body.
The tissue or organ would be transplanted into the patient. The original seed cell is a form of human life; it contains human DNA, whether it comes from a skin scraping or is extracted from the inside of a person's mouth.In order to understand how organ cloning might work, let's first talk about cloning itself.
The most common method of therapeutic and reproductive cloning is somatic cell nuclear transfer (SCNT). SCNT involves removing the nucleus from a donor egg, and replacing it with the DNA from the organism. Benefits of Therapeutic Cloning A major benefit of therapeutic cloning is that the cells removed are pluripotent.
Pluripotent Cells can give rise to all cells in the body with the exception of the embryo. This means that pluripotent cells can potentially treat diseases in any body organ or tissue by replacing damaged and dysfunctional cells. With over , people on the organ transplantation lists in the United States alone, many people need a new organ in order to have a fresh start at life.

A Combination of Technologies. We have proposed that the obstacles of organ replacement might be addressed if various technologies could be pieced together in a way that exploits the advantages of each technology 2, alphabetnyc.com, nuclear cloning (the transfer of a nuclei from mature cells of the individual to be treated into primitive enucleated cells, allowing the reprogramming of DNA) could be.
