Applications of Genetic Engineering - Cloning

By: Melanie K. and Darren M.

The biotechnological system that our group chose to research is cloning. After searching on the Internet we have found what it is, how it works, and what it does. We went to www.thinkquest.com to find most of our information. Cloning is a complex system to duplicate living things such as humans or plants. Many people think that it could someday save human kind although many others think that it is evil.


What it is

Cloning is one or more offspring derived from a single ancestor whose genetic composition is identical. There is no sex involved in cloning. A clone of cells refers simply to the descendants of a single parental cell. The splitting of a single, which is the cause for twins, is an asexual way of reproduction which is natural although could be deliberate. Cloning is basically the reproduction duplicating a living thing to make another.

How it works

Cloning has several different complex ways of reproduction including separating an embryo, nuclear transplantation, taking the cell from a fertilized ovum, and taking the parts of the body. Cloning by separating an embryo works by taking a fertilized ovum, wait until the cell cultivates and separate the cell apart from each other and then putting the ovum back in to the animal. Cloning by nuclear transplantation works by preparing an unfertilized ovum from another female cow and splitting the nucleus apart take the cell out of it using it in cell of another animal.

What it does

Cloning is said to be very productive but is also said to be very evil to many. Cloning can be used to duplicate food or humans in the future for women who cannot produce children and when there is a shortage of food. Cloned food would taste exactly like non-cloned food but would have to pass a test in order to be sold to the public. It would 5-10 more years until humans could be cloned. It duplicates the cell producing an exact replica of the original cell.
