Re: Corn, genetically modified: exactly how is this done in a laboratory

The gene of interest is identified in the donor by a sequence of bases in 
the DNA, this case Bacillus, then excised using enzymes that will clip the 
DNA into pieces. 
The piece containing the gene of interest is then multiplied in another 
bacterium by inserting it into that carrier and then increasing that 
bacterial population.
Once the gene is multiplied several times it is cut out of that genome and 
inserted into the genome of choice, this case corn. 
The corn cells are multiplied and manipulated with hormones to convert the 
cells into corn plants. These plants can then be propagated to produce more 
seed for planting on farms.
The precise details of this transformation and subsequent plants are 
closely controlled by patents and secrecy to optimize profits for the 
developers.
