Cloning


The world we live in is becoming more and more advanced as the years. As a human race we have been making scientific discoveries since the beginning of time. Some of these discoveries are very useful and aid us in our everyday lives. However, there are some discoveries that sound like they are straight out of a science fiction movie. Others lie somewhere in between normal and unrealistic. For example, the notion of cloning. Being able to clone an animal or part of a human being is something that can be hard to wrap your head around. However, this is not a fantasy. Cloning is defined as the process it takes to recreate the exact replica of a cell or tissue. There are three types of cloning that exist in the scientific world; Gene cloning, Therapeutic cloning, and Reproductive cloning. Each type of cloning has a specific purpose.

Reproductive cloning is process of genetically duplicating an organism that exists. Human cloning would be an example of reproductive cloning. Reproductive cloning most commonly works through SCNT, or Somatic Cell Nuclear Transfer. SCNT is the process that takes the nucleus of cell and it is then put into an egg that does not have a nucleus. This then produces an embryo clone which undergoes a series of development with chemicals. This embryo clone is then placed into the uterus of a female animal. The genes of the clone are identical to the genes of the original animal that the cell came from. Therapeutic cloning is mainly for medical conditions. It uses stem cells to grow healthy tissues and organs that can then be used to replace the damaged tissues caused by diseases. Similar to reproductive cloning, therapeutic cloning also uses the process of SCNT. Gene cloning pretty much self-explanatory, the definition is in its name. It is the recreation of DNA segments, or genes.

Each of these areas of cloning have a specific use and place in the world. Eventually, we will be able to clone a whole human being. There is much research that still needs to be done before we get to that point, but we are well on our way. We have been able to clone at least eighteen different mammals, which is a great start. Cloning will progress as time goes on and it will be less of a fantasy thought. One day, it might even become something that everyone gets used to.
