These proteins were known before gene splicing was developed.
The gene splicing is routine, but the project isn't.
Fears that gene splicing might be misapplied to humans have also proved unfounded.
But alarmist warnings about the possible hazards of gene splicing have made the public extremely wary of this selective form of genetic modification.
In fact, gene splicing is the most refined, precise and predictable method of genetic modification because the function of the transferred gene or genes is known.
Just that possibility was emphasized in the 1970's by highly publicized legal battles over whether new organisms created in a laboratory by gene splicing could be patented.
Besides, you think gene splicing is easy?
The field of modern biotechnology is generally thought of as having been born in 1971 when Paul Berg's (Stanford) experiments in gene splicing had early success.
The assessment, which would not be required, would look at whether the new protein introduced into the crop by gene splicing was toxic or would cause allergies.
Researchers who add genes to animal embryos by gene splicing may apply for patents, just like any other inventors.
