For example, some genetically modified insect-free tomatoes gets their ability from the genes of a bacteria called Bacillus Thuringiensis. The scientists first cut out the insect resistance gene from the B.Thuringiensis’s DNA with some restriction enzymes(enzymes capable of cutting specific regions of a DNA), secondly, they’ll insert bacteria’s insect resistance gene into a vector or a plasmid(special bacterial circular chromosome that are separated from bacteria’s rest of the genetic information) with a selectable antibiotic resistance maker gene, which will then be put into another bacteria so that it can go through multiple mitosis, so the genetic information is amplified. After sufficient amount of DNA is gathered, scientist will coat tungsten or gold particles with DNA vectors separated from bacterias, then turn them into teflon bullets, and shot them into tomato plant cells which will allow the genes to integrate into the nucleus. Finally for the last step, cells ar e plated on a selective antibiotic media, that only cells that have incorporated the vector will grow, these cells will then transferred to medium containing plant growth factors.(GSLC. 2013, July 15) Some herbivory canShow MoreRelatedCritically Examine the Geopolitics of Humanitarian Aid Within the 21st Century.2228 Words   |  9 Pageshumanitarian aid within the 21st century.
