This could mean, for example, selecting a gene which leads to the production of a chemical with anti-freeze (11) from an arctic fish, and inserting it into a potato or strawberry to make it frost-resistant. (12) , then, biotechnology allows humans to (13) the genetic walls that separate species.Like the green revolution, (14) some call the gene revolution contributes to the problem of genetic uniformity-some say even more (15) geneticists can employ techniques such as cloning and (16) culture, processes that produce perfectly (17) copies. Concerns about the erosion of biodiversity, therefore, remain. Genetically altered plants, however, raise new (18) , such as the effect they may have on us and environment.
