genetic engineering is taking a gene with a desirable characteristic and transferring it to another organism that will develop the same characteristic
genetic engineering can be done in-between species
it could be used to treat genetic conditions. this is called gene therapy
in gene therapy its hard to transfer the new gene to every cell. The solution to this is to transfer the gene in an earlier stage of development so then as it develops the gene is passed on to other cells.
genetically modified crops pros:
higher yield
disease resistant
can produce more food for less money so good for developing countries
cons of genetically modified crops
not enough evidence to prove that they don't negatively effect our health
how to transfer genes:
isolate gene using enzyme
place in a vector (bacteria or virus)
put into organism so it starts producing the protein the gene codes for
