Chapter 2: What Could Go Wrong-A Partial List
Genetic engineers continually encounter unintended side effects -- plants create toxins, react to weather differently, contain too much or too little nutrients, become diseased or malfunction and die. This chapter describes the process of genetic engineering and twenty-one ways in which it can create unexpected, potentially serious problems.
Excerpt
New DNA chip technology has recently allowed scientists to monitor changes in DNA functioning when foreign genes are inserted. In one experiment, there was a staggering 5 percent disruption of gene expression. In other words, after a single foreign gene had been added through genetic engineering, one out of every twenty genes that were creating proteins either increased or decreased their output. According to Schubert, "while these types of unpredicted changes in gene expression are very real, they have not received much attention outside the community of the DNA chip users." He adds that, "there is currently no way to predict the resultant changes in protein synthesis."
