Manipulating Reproduction - have we gone too far?

Extracts from this document...

Introduction

Manipulating Reproduction - have we gone too far? Scientists have been cloning DNA - the building blocks for all life for decades. For the first time in February 1997 a group of scientists cloned an adult mammal - "Dolly" the sheep. The method used to create Dolly is called Somatic cell nuclear transfer (SCNT). Scientist transferred DNA from the nucleus of a cell taken from a sheep's udder into an egg with its nucleus removed. The egg was then implanted into the uterus of a female sheep. Dolly was a clone of the sheep whose udder cell was used. Many animals have been cloned worldwide including cattle, goats, mice, monkeys. Yet for every animal successfully cloned there are many attempts and many failures. Cloned animals have died at a young age due to defects in their organs, bones or cells. No one has managed to clone a human yet but the possibility of doing so became a step closer to reality. ...read more.

Even attempts to clone cows failed after they developed abnormalities such as growing too big in size and again developing lung problems. Some people think that we shouldn't even being discussing cloning human beings when we cannot even clone a healthy cow or sheep. This goes to show the unethical side of human cloning, as it would be wrong to try and clone a human with the technology need has not even been perfected on animals. This could lead to deformed or sacred people. Cloning humans could lead to the creation and passing on of mutated genes, creating a whole new species of people. People think that experimenting with human cloning whilst knowing the high risk or developing mutated genes is not right and unethical in terms of scientific research, and in terms of basic human morals as well. Cloning humans can also have a social effect. If human cloning did reach stage where they commonplace in society, there would be a lot less genetic variety within society as more and more people will have would have replicas of themselves, instead of creating individuals through pregnancy. ...read more.

Conclusion

. "Human cloning could make it possible for many more infertile couples to have children."5 Couples go through physically and emotionally painful procedures for a small chance of having children. Many couples run out of time and money without successfully having children. Human cloning could make it possible for many more infertile couples to have children than ever before possible. In conclusion, I don't think cloning should be band in all cases. Cloning could be used in various ways to benefit the lives of humans. I think cloning should be allowed but not to clone whole organisms like Dolly but only to clone tissues such as heart, liver, as this will benefit millions of people get an exact match of an organ, without getting it rejected. Some people may believe that we are interfering with nature whereas other people it will help people because cloning can also be used to treat spinal cord injuries, cancer and heart disease. Scientist also believe that they may be able to treat heart attack patients by cloning their healthy heart cells and injecting them into the areas of the heart that have been damaged. ...read more.

    The methods of propagation involved fall into two categories: sexual and asexual. Sexual Propagation This makes for the possibility of endless combinations of genotypes; that is, in the process of fertilisation, the genes of the parent plants recombine randomly, creating new genetic entities similar to but differing from one another and from the parents as well.

    Their cells divide and multiply by the process of mitosis. However, some organisms also reproduce using mitosis, bacteria being a good example. Bacteria are single-celled organisms. When the cell gets to a certain size, it splits into two, the two small cells grow and then divide again into four.
