Abstract
The theory of genetic recombination, the function of gene regulation, and the method of genetic modified plants have been written in recent biology textbooks. According to them, biotechnology contributes greatly to the progress of our medical treatment and food production, but we often find the sign of " no genetically modified food " in various food which makes us somewhat fear of genetically modified food. My students were not exceptional either. But after several experiments, I could find the change in their views on biotechnology and their great concern in genetic recombination. I should like to give more students more encouragement in the study of biology.
