...historic ruling last June invalidating the school's preferential admissions program. Others were not nearly so delighted by his presence. As Bakke arrived, demonstrators shouted, "Affirmative action we demand; unite to smash the Bakke plan!" but the student kept his cool. After a three-hour lecture in molecular and cellular biology, a fellow student handed down his own Bakke decision: "He seems like a pretty nice guy. He's just stuck in class like the rest...
Walter Gilbert '53, American Cancer Society Professor of Molecular Biology, found himself in that very position this August, and the University has quickly taken steps to ensure that a similar mishap does not occur again...
...pulling a U-Haul trailer up one mountain grade too many. Shepherd wears his hair long, sports a scraggly beard, an earring in his left ear lobe and a gold marijuana leaf in his collar. He is going to the University of Colorado in Boulder, where he will study molecular biology. He is impatient to leave Evanston, this cowboy and oil town where they sell bumper stickers that read I'M A ROPER, NOT A DOPER...
Synthesizing copies of these genes, or segments of DNA (deoxyribonucleic acid), was difficult enough. But much harder was the job of getting the genetic instructions inside the potential bacterial factory, a weakened lab strain of the intestinal microbe Escherichia coli. The scientists resorted to a little molecular chicanery. Using their new gene-splicing or recombinant DNA techniques, they hitched their two synthetic insulin genes individually to one of the bacterium's own genes. Then they inserted both the synthetic and the natural material into fresh E. coli. As a result, E. coli's DNA-reading machinery was unable...
Nature could hardly have created anything that seems more innocuous. An invisible and odorless gas, carbon dioxide is a simple molecular linkup of just a single atom of carbon and two atoms of oxygen (CO2). It constitutes a mere fraction of the atmosphere (.03% vs. about 78% for nitrogen and 20% for oxygen) but becomes dangerous to man and other air-breathing creatures when it accumulates in concentrations higher than 10% as, say, at the bottom of deep wells or mine shafts...
