The
DNA (deoxyribonucleic acid) from different organisms is essentially
the same simply a set of instructions that directs cells
to make the proteins that are the basis of life. Whether the DNA
is from a microorganism, a plant, an animal or a human, it is
made from the same materials. 
Throughout the years, researchers have discovered how to transfer
a specific piece of DNA from one organism to another.
A researcher's first step in transferring DNA is to "cut" or
remove a gene segment from a chain of DNA using enzyme "scissors"
to cut at a specific site along the DNA strand.
The researcher then uses these "scissors" to cut an opening
into the plasmid the ring of DNA often found in bacteria
outside of a cell. Next, the researcher "pastes" or places the
gene segment into the plasmid. Because the cut ends of both
the plasmid and the gene segment are chemically "sticky," they
attach to each other, forming a plasmid containing the new gene.
To complete the process, researchers use another enzyme to paste
or secure the new gene in place.
Decades of research have allowed Monsanto specialists to apply
their knowledge of genetics to improve various crops, such as
corn, soybeans, canola, cotton and potatoes.
Our researchers continue to work carefully to ensure that improved
crops are the same as current crops, except for the addition
of one beneficial trait which, for example, protects them from
a particular insect or virus.

through research and technology with new methods of actually
speeding up the process of improving the seeds and the products
we get from them...
