human cloning


Wow ,you look exact like me .How could it be possible? As I know I have no twins however I’m so perplexed to see you like I’m seeing my image on the mirror. I’m cloned of you by the scientist since you are so busy until you can’t manage doing two things at the same time as you can’t split into two. As we know , have naturally occur cloning which are the identical twins are produced. However in fast growing technology it could be done through CLONING. So what  is the meaning of cloning? Cloning’ typically refers to somatic cell nuclear transfer (SCNT). SCNT involves transferring the nucleus of a somatic cell (any body cell other than a sperm or egg cell) into an enucleated oocyte. This simply means an oocyte from which the nucleus and thus most of the DNA has been removed. The oocyte is treated with electric current to stimulate cell division and an embryo is formed. The extracted DNA is inserted into womb o surrogate mother. This was proven as the first mammal Dooly the sheep was cloned using somatic  cell nuclear transfer (SCNT). However human cloning has been the main topic of the cloning debate., so human cloning should be allowed? In my opinion human cloning should be allowed since the pros of cloning outweigh the cons.

In my point of view cloning actually helps in organ replacement. I’m sure there are many of us are suffering  in diabetes. The treatment of course undergoing dialysis  process at least three times a week. It could be painful to be poked all over on your body  with big needles. However the situation can be handled since the vital organs can be cloned too. They can serve as backup system for human beings. Cloning body parts serve as a life saver. For instance the body organ such as  kidney  or heart. There’s no need for us to wait for long period of time to transplant a  kidney since  a cloned of your kidney  from  your own stem cell can be replaced. This method has higher chance to your body to accept the organ compared an organ donated by the donors which has possibly high risk of rejecting it.

Next,  cloning is expansion of opportunities for reproduction. Human reproductive cloning could offer a new means for prospective parents to satisfy their reproductive desires. It is most often presented as a possible treatment for infertility. For those unable to produce embryos of their own, cloning opens up the possibility of using donated eggs (or the woman's own eggs if she is able to produce viable eggs) and then using a somatic cell nucleus of the mother or that of her partner to create a child closely genetically related to one of them. If the female partner's egg is used to clone the genome of her male partner, the resulting child would be genetically related to both parents since the egg contains the mother's mitochondrial DNA. Further, and in particular, cloning could be used to provide homosexual couples with genetically related children.By cloning the genome of a healthy person, parents may avoid passing on inheritable diseases to their child. People might also choose to give their child the genome of a person with good health and other desirable characteristics in order to provide the child with a wide array of possible life plans. Another possible use of reproductive cloning is to help create a child that is a tissue match for a sick sibling. The stem cells from the umbilical cord blood or from the bone marrow of the cloned child could be used to cure the diseased child. Such children, referred to as ‘saviour siblings’, have already been created through sexual reproduction or, more efficiently, through a combination of IVF.

Besides , Cloning of stem cells will provide treatments for variety diseases. Because stem cells can turn into many other cell types with the right prompting, doctors may be able to replace tissues and organs damaged by disease or injury to restore healthy function. If therapeutic cloning is practiced, the fertilized egg cell is harvested. When the cell has itself a few times divided, the valuable embryonic stem cells can be taken from the developing embryo, hereby the embryo is killed.
One issue concerns the use of animal organs for transplantation to human beings, such as using the heart valve of a pig to replace a human heart valve. This kind of transplantation is called a xenotransplant. First addressed by Pope Pius XII in 1956, the Church maintains that such transplants are morally acceptable on three conditions: (1) the transplanted organ does not impair the integrity of the genetic or psychological identity of the recipient, (2) the transplant has a proven biological record of possible success, and (3) the transplant does not involve inordinate risk for the recipient.  A second issue concerns the use of organs or tissues from aborted children (such as those murdered through partial birth abortion procedures). Actually a lucrative organ “Harvesting” industry is developing which utilizes the organs and tissues of aborted fetuses. A critical point here is that these abortions are performed with the intention of utilizing the organs or tissues of the infant, and in direct conjunction with a particular recipient in mind.  Another facet of this issue is when a child is conceived naturally or through in vitro fertilization to obtain the best genetic match, and then born or even aborted simply for organs or tissues. For example, recently a couple conceived a child for the sole purpose of being a bone marrow donor for another sibling suffering from leukemia; while the conceived child determined to be a good match while still in the womb and was born, one must wonder if the child would have been aborted if he had not been a good match. To participate in an abortion to obtain organs, to conceive a child for organs, or to knowingly use organs from aborted fetuses is morally wrong. This issue has even become more complicated with the technological research in cloning. Some researchers hope to grow tissue and even organs from stem cells retrieved from human embryos; however, to do so necessitates the destruction of the embryo. Since human life begins at conception and is sacred from that very moment, such destruction is immoral.
The purpose of therapeutic cloning is to clone things such as organs and tissue for patients in need. Therapeutic applications of stem cells potentially could treat illnesses including: Parkinson’s disease, diabetes, Alzheimer’s disease, stroke, heart attack, multiple sclerosis, blood, bone and bone marrow ailments, severe burns by providing skin grafts, spinal cord injuries, and cancer patients who have lost cells and tissue to radiation and chemotherapy. In addition, stem cells could be harnessed and packaged to deliver gene therapies to specific targets in the body to treat genetic problems.

Last but not least, plastic, reconstructive, and cosmetic surgery could be replaced with cloning. For example, of human cloning and its technology the days of silicone breast implants and other cosmetic procedures that may cause immune disease should soon be over. With the new technology, instead of using materials foreign to the body for such procedures, doctors will be able to manufacture bone, fat, connective tissue, or cartilage that matches the patients tissues exactly. Anyone will able to have their appearance altered to their satisfaction without the leaking of silicone gel into their bodies or the other problems that occur with present day plastic surgery. Victims of terrible accidents that deform the face should now be able to have their features repaired with new, safer, technology.
In the nutshell,Cloning offers remarkable insight into the power of creation that humanity has taken into its fold. One theological analysis holds that humans are co-creators with God; perhaps it is more accurate to say that humans are moving ever closer to a posture of making babies, rather than having babies. Cloning represents a remarkable test of human restraint, wisdom and institutional development, one that will in many ways identify the moral features of 21st century biotechnology.
