“Genetically modified crop plants”

Genetically modified crop plants are crop plants that genetic characteristics have been altered using the techniques of genetic engineering (The American Heritage® Science Dictionary). Genetically modified crop plants accomplishes guaranteeing plenty food supply for the growing population (Whitman, 2000). The first step of genetically modifying a crop is mapping. Mapping is when scientists finds and separate the gene with the preferred genetic characteristics. PCR is the next step when genetically modifying a crop. PCR is when the scientist makes plenty copies of the separated gene (Bionet, 2002). Using a piece of plant tissue, the scientist inserts the wanted genes into the plant’s own genes. The genes can be transferred in three different ways; (1) a gene canon, (2) a soil bacteria, or (3) a material named protoplast (Bionet, 2002). The name for the process of gene insertion is “transformation”. Now that the genes have been transfer the scientist makes a new crop plant out of the genetically modified plant tissue. The scientist checks the transferred gene functions and if the gene shows up in the plant’s progeny (Bionet, 2002). There are many social and ethical issues when it comes to genetically modifying crops. Ethical issues are based off three principles and they are general welfare, people’s rights, and justice. Some people see genetically modified crops as unnatural and disprove of their development (Nuffield Council on Bioethics). Others say it’s unethical to make nature an industrialized type thing because it’s just wrong. The effect GMO’s (genetically modified organism) have on the environment is another ethical concern (Nuffield Council on Bioethics). The ethical debate is that GMO’s are damaging the environment; however others argue that “…genetically modifying technology a new tool which plant breeders are using to achieve their breeding goals more accurately and rapidly (Nuffield Council on Bioethics).”...
