Cloning

Cloning is the process used to create copies od DNA fragments, cells or organisms.

Clearly we have a lot to learn about cloning and we also need to engage in discussion of the ethicalissues of creating life. Perhaps it is fortunate that we do not have this power yet. For example, at one time many individuals of low mental ability were sterilized so that their genes would be eradicated from the population. On the other hand, we must consider the possibility that many troubling diseases such as cystic fibrosis may be able to cured by gene therapy.

A second argument against cloning is the ensuing reduction of genetic diversity for the cloned species. This is already a problem with our domesticated animals. Turkeys have been bred to have more white meat - a larger breast. In fact, the breast is now so large that the male turkeys cannot physically make contact with the female turkeys.

In the positive side, human cloning technology could be used to reverse heart attacks. The scientists believe that may be able to treat heart attack victims by cloning their healthy heart cells and injecting them into the areas of the heart that have been damaged.

More over, with cloning infertile couples could have children. Couples go through physically and emotionally painful procedurs for a small chance of having children.

In conclusion, I think that cloning is very dangerous and riscy process. But it isvery useful technique, especially nowadays.
