Jung Koo Lee MCB 150 Sec. O Assignment 2 10/24/05 1. There is no plant that has an immune system, so the scientists genetically modified some plants to protect themselves from infections. In some crop plants, the scientists found that insertion of the genes, Bacillus thuringiensis, into the plant cells can create the protein toxic that kills the insect larvae, which harms the crops. The vectors that carry these stains of genes are plasmid vectors. They attach to the cell of the plant and introduce the genes into the cell. These plasmid vectors are more efficient in plants because they can replicate independently. Also, unlike other vectors, like virus vectors, the plasmid vectors can accurately introduce the new genes in a single location. 2. Since the plants can’t fight the infections on their own and the insecticides kill the beneficial insects as well, it is good to genetically modify the plants as long as it’s not harmful. Changing a little part of the DNA sequence in the cell of a plant is the key to more productivity and better quality of the crop. The farmers won’t have to worry about bad harvests, and a research shows
