Genetic Engineering

What is Genetic Engineering?
Genetic engineering is the changing of an organism's genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species.
Example of Genetic Engineering
These pictures represent Genetic Engineering because it shows how they are changing the traits of the subject. This picture depicts a needle being injected into the tomatoes to change their traits, like making them larger,making the color brighter, and putting preservatives in them to make them last longer.
How did Genetic Engineering develop?
Genetic engineering caused by human activity has been happening since around 12,000 BC, when humans first began to domesticate organisms.
who developed it and when?
Genetic engineering as the direct transfer of DNA from one organism to another was first accomplished by Herbert Boyer and Stanley Cohen in 1973.
Where did it start?
Genetic engineering started with artificial selection. Meaning breeding specific animals to get another animal. Sheep and goats were domesticated around 8,000 BC in the Fertile Crescent, while pigs appeared in China about 7,000 BC, yaks in Tibet about 5,000 BC and horses in Eastern Europe around 4,000 BC. The first domesticated bird was the rock pigeon, appearing in Greece, Egypt and Mesopotamia around 3,000 BC and the first domesticated fish was probably carp, raised as food in China around 1,000 BC.
What techniques did the developer use to determine the topic content?
Genetic engineering became possible when scientists discovered the most common vector used in genetic engineering which helped scientist find these techniques, for example, recombinant DNA technology, microinjection, bio ballistics, electro and chemical proration
to enable scientists to change the traits of their subjects.
