Have you ever thought what is it about cloning that is so important that scientists all over the world are still experimenting, up till today? Why do we have to clone things? Well, there's definitely a reason.
One reason is to help those people who want a child but are unable to. Infertile couples are able to have a kid as reproductive cloning does not require the fusion of the sex cells.
Another reason that cloning can benefit us is that it can help treat diseases. Therapeutic cloning can be used to treat degenerative diseases like spinal cord injury, organ failure or the nervous system. It would be able to save so many people with diseases or injuries.
Cloning would be able to replace the defective genes in someone that causes illness to him or her. The defective can be replaced with healthy ones.
One other example is also the reason for cloning the famous Dolly the sheep. Dolly had been genetically modified to produce milk that contains a human protein essential for blood clotting and it can be given to humans whose blood does not clot properly.
Cloned animals can also be used to test new drugs and treatments. It is very useful as cloned animals are genetically identical so the response to the drugs would be the same, instead of using animals with all different genetics.
If cloning really becomes successful in the future, all the things listed above can be achieved and it can benefit us. However, although there are many benefits, there is also a number not-so-good points. There is also the issue of moral and ethical implications of cloning and some people are against the idea of cloning. I hope this has helped you to understand more about cloning and its benefits.
