Detailed explanation-1: -Discovery of the structure of DNA This was a key moment in the lead up to genetic engineering because in order to edit genetic material, its structure had to be known.
Detailed explanation-2: -The techniques employed in genetic engineering have led to the production of medically important products, including human insulin, human growth hormone, and hepatitis B vaccine, as well as to the development of genetically modified organisms such as disease-resistant plants.
Detailed explanation-3: -Other techniques include using electroporation and biolistics. In some cases, transfected cells may stably integrate external DNA into their own genome, this process is known as stable transfection. To create transgenic animals the DNA must be inserted into viable embryos or eggs.
