cloning

Many animals are cloned over the past fifty years. Itfirst started in the 1950s when scientists were able to clone frogs, producing identical individuals that carry the genetic characteristics of only a single parent. Then, mice werefirst successfully cloned in the 1980s. These animals are small animals that do not have complex body organs like human beings body. Therefore, the cloning of a small animal is far more easier than cloning an adult mammal with complex body organs. Many rumors had been spread about many human beings that had been cloned. But until now there are no evidences that the creation of a human being clone had been successfully achieved.

The experiment that I would like to discuss is thefirst success in cloning an adult mammal. It was achieved by a team of British researchers led by Ian Wilmut at the Roslin Institute in Edinburgh, Scotland, in 1996. After having already produced clones from sheep embryos, they were able to produce a lamb, named Dolly. To create the clone, the nucleus of a cell from the mammary gland which is the milk-producing gland characteristic of all female mammals from an adult sheep was implanted in another sheep’s unfertilized egg whose nucleus had been removed. The secret with the nucleus is that it contains all of the information about creating the human body called the DNA. The DNA 30,000 to 40,000 genes .The nucleus is then implanted into the recipient egg. An electrical current is applied to simulate the burst of energy that occurs during fertilization. The egg begins dividing normally and becomes an embryo, which is implanted into another ewe. The lamb that is born is a clone of the donor of the original mammary cell. The egg spends about seven months until the egg develops into a baby lamb.

Cloning

Cloning

To some people the word “cloning” is a frightening thig. Cloning is the scientists of the world new quest. It is taking a cell from something and making the exact same thing that the cell came from. There are many things that cloning can do that would sound like it could help. Then there are things about cloning that sound like it could destroy the world. Is cloning going to be ok and stay where it’d at? Or is it going to far when they finally clone a human being.

Cloning has been around for a while. For a long time scientist have played with mice and tried to clone them. And for a long time they were unsuccessful. Finally, they try to clone another mammal which happened to be a sheep. They tried around three hundred times before they were successful. They named the sheep Dolly. It was instantly all over the news. Everyone knew that a sheep had been cloned. Some were in aw at our developing technology, and some were in shock and fear at to what was to come next.

Cloning could come very useful to the world. Cloning could be used to make better breed of cows and pigs for us to harvest. They could come with fewer diseases and produce better milk or meat for us to use. They could make pets that live longer so you don’t have to worry about your dog’s health and just enjoy its company. Cloning doesn’t sound like such a bad idea when it comes to animal but, when it comes to humans it’s a different story.

Just the thought of a human being cloned scares most people. What would you do if you saw yourself walk by youself on the street? What if the government got your DNA and started a whole army! If it took hundreds upon hundreds of time to get a sheep to be cloned think of how many unborn children could die because something went wrong. Also think about if they are born. Will they live like normal humans? What if they are fine when they are born but later become sick with some disease caused by the fact that they were made? Do…
