...when RCA Records executive Michael Omansky approached Phone Programs about publicizing D.J. Jazzy Jeff and the Fresh Prince, a new rap duo. AT&T provided the necessary 900 area-code number. The result was an immediate hit. Spurred on by a TV ad campaign, some 2.5 million rapsters have rung up Jazzy Jeff and friend since the debut of their two- minute talkfest last June. The cost: $2 for the first minute, 45 cents a minute thereafter. Other hot lines soon followed. Now word of Phone Programs' success has got around. "People from every walk of music are coming...
...what a wondrous string it is. As Watson and Crick discovered in 1953, DNA consists of a double helix, resembling a twisted ladder with sidepieces made of sugar and phosphates and closely spaced connecting rungs. Each rung is called a base pair because it consists of a pair of complementary chemicals called nitrogenous bases, attached end to end, either adenine (A) joined to thymine (T) or cytosine (C) attached to guanine...
Fundamental to the genius of DNA is the fact that A and T are mutually attractive, as are C and G. Consequently, when DNA separates during cell division, coming apart at the middle of each rung like a zipper opening, an exposed T half-rung on one side of the ladder will always attract an A floating freely in the cell. The corresponding A half-rung on the other section of the ladder will attract a floating T, and so on, until two double helixes, each identical to the original DNA molecule, are formed...
...stuff of which high drama, as well as low comedy, is often made. John Tower had served on the powerful Armed Services Committee for 20 years, four of them as its strong-willed chairman. Now a majority of former colleagues blocked his efforts to climb one more rung in his distinguished career. Moreover, and perhaps most demeaning, they ostensibly turned against him because of questions about his life-style, although his professional activities also worried them...
...Kadrmas decision also contradicts a precedent which bars any state action "[promoting] the creation and perpetuation of a sub-class of illiterates with in our boundaries." In our society, education is the crucial first rung of the social ladder. It is difficult to imagine anything that would more effectively create a "sub-class of citizens" than making education inaccessible to the poor...
