Bau Proficiency Reading Sample 1
The first two decades of this century were dominated by microbe hunters. These hunters had
tracked down one after another of the microbes responsible for the most dreaded scourges of many
centuries: tuberculosis, cholera, diphtheria. But there remained some terrible diseases for which no
microbe could be incriminated: scurvy, pellagra, rickets, beriberi. Then it was discovered that these
diseases were caused by the lack of vitamins, a trace substance in the diet. The diseases could be
prevented or cured by consuming foods that contained vitamins. And so in the decades of the
1920-39s and 1930-39s, nutrition became a science and the vitamin hunters replaced the microbe hunters.
In the 1940-39s and 1950s, biochemists strived to learn why each of the vitamins was essential for
health. They discovered that key enzymes in metabolism depend on one or another of the vitamins
as coenzymes to perform the chemistry that provides cells with energy for growth and function.
Now. these enzyme hunters occupied center stage.
You are aware that the enzyme hunters have been replaced by a new breed of hunters who are
tracking genes – the blueprints for each of the enzymes – and are discovering the defective genes that
cause inherited diseases – diabetes, cystic fibrosis. These gene hunters, or genetic engineers, use
recombinant DNA technology to identify and clone genes and introduce them into bacterial cells and
plants to create factories for the massive production of hormones and vaccines for medicine and for
better crops for agriculture. Biotechnology has become a multibillion-dollar industry.
In view of the inexorable progress in science, we can expect that the gene hunters will be replaced in
the spotlight. When and by whom? Which kind of hunter will dominate the scene in the last decade
of our waning century and in the early decades of the next? I wonder whether the hunters who will
occupy the spotlight will be neurobiologists who apply the techniques of the enzyme and gene
hunters to the functions of the brain. What to call them? The head hunters. I will return to them
later.
