...homes a year in Mission Viejo, Calif..and the suburbs of Denver. But most of all. Philip Morris sells cigarettes--Marlboro, Merit, Virginia Slims. Benson and Hedges. Parliament, Alpine, Saratoga 120s and others. Machines in the Richmond facility put tobacco into paper tubes, hand the cigarettes, cut them, insert filters, box them, put the boxes into the cartons and the cartons into cases and the cases into trucks. How many? These figures are from one factory- 600 million cigarettes a day, 140 billion cigarettes a year. Overall, Philip Morris churns out 191 billion cigarettes a year--about 30 per cent...
Genetic engineering, an ensemble of techniques to join bits of DNA and insert them into bacteria to make large quantities of potentially valuable proteins, made a great splash last year when stock from Genentech Inc. went public and jumped $45 per share during its first day on the market. The slightest technological advance still sends prices leaping. Genentech jumped $7 in one day two weeks ago when workers announced a new process to make interferon, a supposed cancer-fighting protein. Genentech will now use yeast to produce the human protein rather than bacteria. It doesn't seem like a major...
...made from increasingly costly petroleum products. But scientists using plasmids have already cloned some of the nitrogen-fixing genes found in bacteria. And in an experiment at Cornell, a complete set of 17 such genes was transferred from bacteria to yeast, a slightly higher organism. The ultimate goal: to insert these genes in the plants themselves...
Like Berg, Cohen wanted to insert new genes artificially into bacteria. But where Berg resorted to a virus as his transport system, Cohen opted for plasmids, which he had been studying in his lab. As he listened to Boyer's description of his work that night in Waikiki, however, Cohen realized that there might be a short cut. Boyer and his associates had found a so-called restriction enzyme that cuts DNA precisely at predetermined points, and performs this surgery in an especially helpful way: at each end of the severed, twin-stranded molecule, it leaves an extra...
