Passage Two
Gene therapy and gene-based drugs are two ways we could benefit from our growing mastery of genetic science. But there will be others as well. Here is one of the remarkable therapies on the cutting edge of genetic research that could make their way into mainstream medicine in the coming years.
While it’s true that just about every cell in the body has the instructions to make a complete human, most of those instructions are inactivated, and with good reason: the last thing you want for your brain cells is to start churning out stomach acid or your nose to turn into a kidney. The only time cells truly have the potential to turn into any and all body parts is very early in a pregnancy, when so-called stem cells haven’t begun to specialize.
Yet this untapped potential could be a terrific boon to medicine. Most diseases involve the death of healthy cells--brain cells in Alzheimer’s, cardiac cells in heart disease, pancreati
A. there will inevitably be human cloning in the coming year
B. the potential to make healthy body tissues is undoubtedly a boon to human beings
C. it is illegal to clone any kind of creatures in the world
D. it is legal to clone any kind of creatures in the world except human
