...muscle-building and morale-building exercises to help him ignore the stares of passersby. Said he: "I hate to leave this wonderful hospital, but I am a grownup now, so I must face it." At 7 ft. 7 in. he is indeed grown up, but mercifully, he will probably grow no more...
...still alive, and some who gave it form are still only middleaged. Outstanding among them: Professor George Wells Beadle of Caltech, who did most to put modern genetics on its chemical basis. Geneticist Beadle is a mere 54. In his working lifetime he has seen genetics grow from a small, rather baffled specialty into a central, exciting science that is drawing the rapt attention of chemists, physicists, mathematicians, even astronomers, as well as nearly every type of biologist...
...teacher in Brünn (now Brno, Czechoslovakia), began experimenting with peas in the monastery garden. Mendel found that the parent plants transmitted their characteristics to their descendants in a predictable, mathematical way. When purebred red-flowered peas, for instance, are crossed with white-flowered ones, all the seeds grow into plants with red flowers. But when these red hybrid plants are crossed with each other, one-fourth of their offspring bear white flowers...
...sprouted hopefully but did not grow. These were the interesting spores. They acted as if they were trying to grow, but needed something that they could not get from the agar or produce for themselves. So when a microscope showed such a spore, it was tenderly fed with vitamins, amino acids and other growth-fostering chemicals in hope of making it perk up and grow normally...
...start of the experiment, Beadle and Tatum resolved to make at least 1,000 tries before giving up. Such perseverence was not necessary. On the 299th try they found an ailing spore that needed only vitamin B-6 (pyridoxine) to make it grow lustily. When it had mated with a normal mold, it transmitted its need for vitamin B-6 to its descendants in the proper Mendelian manner for a single mutated gene...
