An essay on the controversies surrounding clones and cloning

Other advocates of cloning speak to the potential benefits to non-humans: This effectively took the place of SCNT as a reprogramming technology, as it was accepted as a less controversial form of deriving pluripotent stem cells.

Embryologists had long been grappling with understanding how the vast diversity of cells in the body could be derived from a single fertilized egg cell. Worse things are happening in our country where lacks of female fetuses are destroyed by parents, eager to have a male child, with the connivance of doctors.

One side believes that knowledge is value-free: In addition, the development of induced pluripotent stem cellswhich are derived from somatic cells that have been reprogrammed to an embryonic state through the introduction of specific genetic factors into the cell nuclei, has challenged the use of cloning methods and of human eggs.

The Vatican Archbishop said that the church opposes any form of human conception that was not born from an act of love between husband and wife.

Scientists were puzzled by the concept of cellular differentiation, the ability of a fertilized egg cell to become a unique cell type within the body [1].

Controversial essay on Human Cloning - A dangerous invention

Most supporters also argue that the embryo demands special moral consideration, requiring regulation and oversight by funding agencies. In companion animals, it is improbable that the very few pets likely to be cloned will have an effect on the population in general.

Controversies in Science: Cloning

The golden standard for deriving pluripotent cells is in fact an embryonic stem cell derived from an embryo that has been made from the fertilization of an egg.

Scientists have since successfully derived embryonic stem cells from SCNT human embryos. To start, scientists began by studying the pluripotent cells—the embryonic stem cells.

Human Cloning: Unmasking the Controversy

Technology, Politics, and Ethics as Anthropological Problems. The scientists have now started talking of designer babies, which make it theoretically possible to genetically engineer our children, with added height or intelligence and removing defective genes or disabilities such as cystic fibrosis or alcoholism.

Cloning, albeit a straightforward solution to generating new organs, has become taboo in itself, causing the path to duplication to become less linear and more complicated for the scientist. In eukaryotic organisms organisms possessing a cell nucleus such as humans, all the cells that undergo mitosissuch as skin cells and cells lining the gastrointestinal tractare clones ; the only exceptions are gametes eggs and spermwhich undergo meiosis and genetic recombination.

Clones seem to have higher risk of genetic problems, shorter lifespan, and other health issues. 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.

Although a simple idea, scientists and physicians have struggled for more than 50 years to understand how we can manipulate our cells in order to replace or regenerate our bodies.

Towards the Future Cloning technologies have the potential to drive medicine into an era of regeneration. In Novemberthe scientists were able to clone the first human embryo. SCNT was deemed as controversial because it generates embryos whose embryonic stem cells are then harvested to generate pluripotent cells in a dish.

Stem Cell Research and Human Cloning. A cloned embryo intended for implantation into a womb requires thorough molecular testing to fully determine whether an embryo is healthy and whether the cloning process is complete. Making heart cells from pluripotent stem cells would allow us to regenerate the damaged heart.

Later, Spemann, who was awarded the Nobel Prize for Physiology or Medicine for his research on embryonic development, theorized about another cloning procedure known as nuclear transfer.

Looking back, in more than a half-century of research, reprogramming experiments have demonstrated the remarkable flexibility of our cells to be converted into different cell types that can serve as the basis for regenerative therapies. Human cloning could be misused to destroy the existing humanity and civilization.

InIan Wilmut effectively derived the first embryonic stem cells using SCNT in a mammal and effectively cloned the first mammal—Dolly the sheep [4]. Many organizations have called for a moratorium on research into human cloning, concerned about ethical issues.

You begin to notice one day that the computer freezes more frequently, and you continue to have problems. The embryo develops into a fetus that is then carried to term.

Cloning Essays (Examples)

Prior to implantation of the fertilized egg into the uterus of the surrogate mother, the inner cell mass of the egg can be removed, and the cells can be grown in culture to form an embryonic stem cell line generations of cells originating from the same group of parent cells. 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 stem cell therapies.

In macaque monkey embryos were cloned by SCNT, but those clones lived only to the blastocyst stage of embryonic development.Cloning The most significant problem our world has with newfound controversies is that most people take one side on the issue before they become educated on the topic at hand.

This is the same problem that I see with the controversial issue of cloning. Cloning technologies have the potential to drive medicine into an era of regeneration. If we define human life as beginning when a cell has the potential to become a full human being, then we may run into difficulties when we consider that essentially any cell in our bodies has the potential to become a full human being.

However, despite the benefits of therapeutic cloning, there are huge controversies surrounding the topic. One argument against therapeutic cloning is that creating stem cells on a large scale would require the use of vast amounts of human eggs. The Controversy Over Cloning The biggest cloning controversies center around human cloning.

Many organizations have called for a moratorium on research into human cloning, concerned about ethical issues. Cloning is an advance technological invention for producing a genetic twin of a living thing, an organism that starts life with the same genes as its parents.

Feb 28,  · Cloning first began as a scientific experiment to clone animals, and the first clone, Dolly the sheep, showed that the process worked. Cloning is actually a natural phenomenon, but it has become so controversial that it is often viewed as an unnatural way to create new life.
