2. Genetic Engineering =
It’s the manipulation of genes that can be transferred
from one species to another
Genetic Mutations =
Genes that are moved from one organism to another
5. Way #1
Transfer the selected genes
between the species by
attaching the transgene and
other necessary genes to
transfer a plasmid.
The transfer plasmid is then
made in a test tube and
inserted into the bacteria
After the transfer plasmid is
inside the host, it releases
the plasmid.
The host cells DNA takes in
the information.
6. Way #2
The transgene copies and the associated genes are
painted onto microscopic metal particles.
The microscopic particles are shot into the nucleus of the
host cell with a “gene gun.”
After the tiny metal particles enter the plant cell’s nucleus
the transgenic DNA inserts itself into the host DNA.
7. Reduce the use of pesticides,
herbicides, and fertilizer
Improve the use of available land
Produce future specialty crops
Health benefits: increased levels of
antioxidants and vitamin C
Last longer, and is tougher (ie:
Tomato)
8. Costs more
Might be awhile before sold on the market
Questionable about health affects
Environmental risks
Allergic reactions
Reduction in crop diversity
