|
|
the observation of nondominant alleles
|
|
|
the discovery of lethal genes
|
|
|
the formulation of Punnett squares
|
|
|
the structure of the DNA molecule
|
Explanation:
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: -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.
Detailed explanation-3: -Genetic engineering allows scientists to move desired genes from one plant or animal into another.
