10、 embryos before one stays in the womb.Cloned embryos would give them many more embryos to implant. But the technique could also be used for other purposes. Parents might freeze embryos cloned from their children so that they could be replaced if any of them died.The clones would also be ideal donors
11、 if the children needed organ transplants. Another possibility: Childless couples could go to a bank of frozen embryos and choose a child just like one whos already living.

17、 used to treat certain cancers. Antibiotics are sometimes called“ wonder drugs because they can cure many diseases that once were often fatal. The number of deaths that are caused by pneumonia and scarlet fever has declined drastically since people began using antibiotics. 2. There are more than 70
18、clinically useful antibiotics, Antibiotics fight pathogenic microbes and cancer cells by interfering with their normal cell processes. In most cases, this interference can occur in one of three ways: prevention of cell wall formation, disruption of the cell membrane, and disruption of chemical proce
19、sses. 3. The contents of bacterial cells are enclosed in a membrane that is surrounded by a rigid wall that prevents the cells from splitting open. Penicillins and some other antibiotics destroy pathogenic microbes by hindering the formation of this wall. Human cells do not have nor need rigid cell
20、walls and so are not damaged by these antibiotics. 4. Some antibiotics, including nystatin, disrupt the cell membrane of certain microbes. This membrane controls the movement of materials in and out of the cell. If the membrane is disrupted, vital nutrients may escape from the cell, or poisonous sub
21、stances may enter and kill the cell. But the membranes of human cells are not affected because these antibiotics disrupt cell membranes that contain elements found only in microbial cells. 5. All cells produce proteins and nucleic acids, which are vital to the life of any organism. Some antibiotics
22、fight disease by interfering with the chemical processes by which these substances are produced.For example, streptomycin prevent certain kinds of microbes from producing proteins, and rifampin interferes with the formation of nucleic acids. Human cells produce proteins and nucleic acids in much the
23、 same way that microbial cells do. But these processes differ enough so that some antibiotics interfere with chemical activities in microbial cells but not in human cells. 23 A. Autibiotics destroy pathosenic microbes by preventing the formation of the walls surrounding the membranes of the microbia
24、l cells that prevent the cells from split- ting open. B. More than 70 clinically useful antibiotics have been in- vented to fight pathogenic microbes and cancer cells by interacting with their normal cell processes. C.
