...made piece of machinery is nearly so complex. Capable of countless chemical reactions, it can fend off attackers, reproduce itself and perform all the other activities that characterize life. In laboratories around the world, thousands of researchers are busily trying to understand-and in some cases, duplicate-the cell's vital chemistry. Last week two teams of scientists made significant advances toward those goals...
...task was formidable. Hidden in the chromosomes, genes are basically sections of an extremely complex molecule called deoxyribonucleic acid (DNA). Twisted together like a spiral staircase, or double helix, the twin strands of the DNA molecule are linked by "steps" composed of pairs of mutually attracting chemicals, or bases, called nucleotides. DNA contains only four different kinds of nucleotides, but they can be arranged in an endless variety of complex sequences. Each complete sequence-some including thousands of steps on the molecular staircase-is a single gene containing a coded message of heredity. With that message, the gene can order...
...model, Khorana picked a relatively simple gene from the common yeast cell; its nucleotide sequence is only 77 steps long. But those 77 steps made the building process immensely complex. Adding one lab-made nucleotide at a time in complex chemical processes, Khorana's team patiently assembled small, single-stranded segments of the 77-step chain. After each step forward, the scientists had to backtrack: every new combination had to be unraveled in order to check that the nucleotides were still in the right sequence and had not been damaged by chemical side effects. When enough strands had been...
...Arkin's complex, triumphant performance is due in part to good genes ?he looks more like Yossarian than he does like Arkin. In part it is due to a virtuoso player entering his richest period. But in the main it is due to the quirky talent of Director Mike Nichols, whose previous successes have been wrung largely from the bland and facile. It is as if Neil Simon were to turn out Endgame or Peter Sellers to turn into Falstaff...
...University of Chicago, like many another converted introvert, he woke up to performing. Wit is far more often a shield than a lance; " Mike set up a complex of defenses that (TM) made him the fastest tongue in the Midwest. The second fastest was a hostile = chick named Elaine May. It was love I at first fight. "Elaine held me like an autistic child," Nichols remembers. The child bride he had taken at 19 was cast off. Elaine became a surrogate, although, says Mike, "it was much too serious for marriage." And much too funny not to play...
