Genetic Engineering

Two years ago Scottish scientists announced that they had successfully cloned a sheep. They named it dolly and it was an exact copy of the original sheep. Is cloning morally right? Is it ethical? Some people think that it is wrong and that it shouldn?t be practiced on any animal. In this report I will tell you about genetics, cloning and whether I think it is wrong or right.

Genetics Is the study of a persons genes or ancestry. Genealogists can tell you where your ancestors immigrated to America from. They can also tell you why you have a certain color hair or why you are shorter than everyone. Genes will determine how short you are and what your personality is like. They are the building blocks of life. You will get a gene from your mom and your dad. they will combine to make a single gene. Gene types are represented by letters, capital letters and lower case. A capital letter stands For a dominant trait and a lower case stands for a recessive trait. When a capital letter and a lower case letter are mixed it is called a hybrid and the dominant trait will take over and the baby will turn out like the parent with the dominant trait.

Cloning is a method of making a copy of a cell. the cell may belong to a animal or a human. In a very brief way it works like this. You take an egg, and remove the nucleus, and by doing this you are removing of the egg?s genes. Then, you take a nucleus from a cell belonging to the first sheep. You put the cell?s nucleus into the egg. You then electrically trick the reconstructed egg into believing that is a fertilized egg so it will divide and become an embryo. When the embryo has reached a certain stage, you transfer it to the uterus of a surrogate mother. Then the clone is born the usual way, looking and acting just like a regular healthy baby. That?s how Dolly the sheep was created. Today Dolly is a normal, healthy sheep, who has had four children, and they are just as healthy.

After researching the topic, I believe that cloning is okay. I think that some day it will lead to great breakthroughs in the medical and scientific worlds. Of course that I do not think that there should be any restrictions to practice cloning. I think that you must have permission from the government and you must have a Medical diploma. Also, you must have watched the procedure at least 3 times and take a lengthy test on the process of cloning. Right now there are many laws against cloning and it is outlawed in every country.

All in all, cloning is safe and easy process. It is not cruel and should be legal to practice, but, of course not without restrictions.
