...with Impurities. Taking natural DNA from a simple virus called Phi X 174 (which consists only of a DNA molecule surrounded by a protein sheath), they added it to the brew as a template, or blueprint, to guide the assembly of the synthetic molecule. Under the influence of the DNA polymerase enzyme, the four basic nucleotides aligned themselves in codelike combinations alongside the natural DNA molecule. Eventually they formed a strand consisting of about 6,000 nucleotide units that was a mirror image of the corresponding strand in the natural molecule. Then, using their mirror-image molecule as a template...
...Plasma Sheath. During the brief instant of the nuclear explosion (which lasts only five ten-millionths of a second), X rays traveling at the speed of light emanate from the center of the blast. Although their effect diminishes sharply at increasing distances even in the vacuum of space,* the X rays from a one-megaton blast are intense enough to destroy an ICBM caught within a sphere extending two miles from the exploding ABM warhead...
Striking the ICBM, X rays instantaneously ionize a thin layer of its outer casing, causing the formation of a sheath of hot gas, or plasma. But only a small portion of X-ray energy is used to form the plasma sheath. Most of the remainder is converted into a shock wave that races through the missile. At a distance of two miles, the impact of the shock wave on a 6½-ft. dia. 30-megaton warhead would be equivalent to the explosion of 2 or 3 Ibs. of TNT within the missile, which may be enough...
Staff members of Fair magazine are viewing the body of Miss Blaisie, an editorial secretary who lias died at the age of 30. The corpse is fitted with a modish sheath dress and has a typewriter on its lap. "You look odd," says Bahs aside to Gianna. She replies: "Don't you think it repulsive to see our Blaisie, our dignified Blaisie, with a bare shoulder and her Underwood on her belly...
Without uttering a word, Tsafendas drew the dagger out of its leather sheath, plunged it three times into Verwoerd's chest and once into his neck. The House looked on in horror, too stunned to move. Verwoerd tried to raise one arm to protect himself, then, confused, used it to brush back his hair. He slumped over, blood spurting through his shirt...
