Cloning: medical breakthrough or a step to far?

Extracts from this document...

Introduction

Cloning: medical breakthrough or a step to far? In this day and age there are three types of cloning available these being: Embryo cloning: This is a medical treatment that produces two or more identical embryos. From a fertilised Embryo one of more cells are removed and then encouraged to grow into one or more duplicate Embryos. Thus identical embryos are produced with identical DNA structures. Adult DNA Cloning: Also known as 'Cell Nuclear Replacement' is the procedure used to clone Dolly the sheep. The process involves the DNA of an embryo being removed and then replaced by the DNA of an adult of the same species. This embryo is then implanted into a womb where it is left to develop fully. Therapeutic Cloning: This procedure starts off like 'Adult DNA Cloning' but instead of the embryo being left to develop fully, after 14 days its stem cells are removed form it. These stem cells are removed with the intent of inducing them to grow into tissues or whole organs for use in transplants back into the person who supplied the DNA. ...read more.

These though all have ethical reasons against them. There is a question whether it is right to be able to just bring a person into the world to provide 'spare parts'. Also there is a question of whether it is right to eliminate genetic faults, these could be stages of evolution which might seem wrong now but ultimately could be beneficial to humans in the future. (Sources 5 and 6) Adult DNA cloning brings with it again man ethical and moral concerns, but these are also counteracted by the medical gains this method could also be used beneficially in the aid of providing people with children. Couples in which the male is sterile could use their or their partners DNA and have it cloned through this method to produce offspring of their 'bloodline'. This reason though has many arguments against it, for example the question of why the family can't adopt a child, as there are many who have been abandoned and who could provide a child for them to love and love them back rather then cloning another. Also this reason could present many social and psychological problems for the cloned child; because by looking at the parent from whom they are cloned they would be able see their possible future. ...read more.

Conclusion

Many 'pro-life' supporters believe that an embryo is a human person and as such all of the cloning methods would be assaulting the human, and in therapeutic cloning murder of the human. This though in the case of the therapeutic cloning is justified by scientists who say that the nervous system does not develop until the 14th day and so as the embryos are terminated before then they would feel nothing. Cloning needs significant of the techniques and procedures so that conclusive and reliable results are gained before it is even justifiably considered in being widely implemented on humans. Even though stem cells are used in therapeutic, it would be the most accepted cloning method of the three by society. This is because only organs or tissues are produced and no actual cloned humans, who society may or may not reject, as this is a question that cannot be answered until or if it actually occurs. Overall cloning can definitely be seen as a medical breakthrough as it represents advances in technology and knowledge of genetics. Whether or not it is a step too far is a contentious issue and which will always be present in some people's views. ...read more.
