Why did genitic engineering begin?

Answer 1

Genetic engineering has been around for a long time, such as selective breeding of animal stocks, but the purposeful tweaking of DNA has only been around since the 1970s. For animal breeding, breeders chose the features they most liked in the animal and bred those that exhibited these features.

For the more modern version, genetic engineering was started for various reasons. Genetic engineering found a way to produce artificial insulin, produced by bacteria, in order to meet the requirements of growing numbers of diabetics. Crops were engineered to withstand pesticides and herbicides so that farmers could spray the crops to kill the insects and weeds without damaging their plants.

Answer 2

The discovery that signalled towards the birth of genetic engineering was DNA cloning. Stanley Cohen and Herbert Boyer discovered this in 1973. Herbert and Stanley invented genetic Engineering as well. They discovered this in April 1997. However its said that farmers and breeders has been doing it for thousands of years, genetically engineering with humans was discovered in 1997.

Answer 3

History of genetic engineering. Genetic recombination caused by human activity has been occurring since around 12,000 BC, when humans first began to domesticate organisms. Genetic engineering as the direct transfer of DNA from one organism to another was first accomplished by Herbert Boyer and Stanley Cohen in 1972.

Answer 4

Genetic engineering is done to produce genes

Answer 5

a type of history.
