...denied that he had made any such link, the denials contradicted the plain sense of his words. "There was a new pitch and nuance to the U.N. speech," acknowledged a well-placed Administration official. "If our coalition succeeds in getting Iraq out of Kuwait, there may be just the nucleus of something we can work with on the Arab-Israeli issue...
Each gene consists of a segment of the DNA that is found in the nucleus of every one of the body's 100 trillion cells (with the exception of red blood cells, which have no nuclei). And each gene is responsible for the manufacture of a particular protein that contributes to either the structure or the functioning of the body. If the gene is defective, protein synthesis will be faulty and a deformity or genetic disease will result...
...have some great atheletes on this team," Caples said. "We have a nucleus of returning players in the middle, and we're very steady with both of our goalies. The freshmen have also provided us with a depth of options. Consistency is the only difference between us and other teams...
...goal is grand -- and maddeningly difficult to achieve. Ever since Watson and Crick first deciphered the structure of DNA in 1953, doctors have had visions of treating disease not from the outside, with drugs or scalpels, but from the inside, by altering the primal instructions tucked in the nucleus of living cells...
...experiments rely on a technology that has evolved over the past 12 years. Each uses a virus to act as a kind of biological taxi to transport a desired gene into the nucleus of human blood cells. In one experiment, a team led by Dr. Steven Rosenberg proposes to treat malignant melanoma, a form of skin cancer, with blood cells that have been genetically altered to transform them into tiny factories for a tumor-killing protein...
