Transgenic Animals. These are animals that are genetically engineered in order to produce something or do something that they wouldn't usually produce or do.

Introduction:

Imagine a perfect world with no sicknesses or diseases? With no bad or violent attitudes? A world where you could design your kids however you wanted? A world where food would always taste good? All this became a possibility when Genetic Engineering was invented. By altering the humans, plants, or animals genes this world could become a reality. Except it would be no fun, and mostly not ethical or moral. You would be playing God. But there are a few things Genetic Engineering would improve, for example health. Using genetic engineering in animals could make health advances. In order to understand this you have to know what Genetic Engineering is, how it is applied to animals, what uses or advantages does this have, and how it should be used but in a careful and regulated manner.

-Internal Preview: We will start with the basics, what genetic engineering is.

Body:

I. In the genetic engineering of animals lots of factors are involved.

A. First of all you have to know what DNA is.

1. All living organisms are made up of tiny cells.

2. Cells contain a nucleus, which contains DNA.

3. DNA is what contains the genes.

B. Genes are what determine everything in a living organism.

1. From hair color to diseases.

2. When cells reproduce the DNA strands have to be copied exactly.

C. Cells reproduce by splitting.

1.One cells splits into two cells.

2. When a cell is splitting it makes an exact copy of the DNA in the nucleus so that the new cells will have exactly the same information and nothing in the body will be altered or changed.

3. Sometimes a mistake takes place in cell reproduction and the DNA is not copied exactly.

D. These mistakes are called mutations.

1.Some mutations can...
