THE DNACHIPS
Introduction
Imagine a device no bigger than a credit card that could extract your DNA from a drop of blood and map your entire genetic code while you wait. Within a short period of time the proneness to any illness or disease could be mapped and studied. This is not a snippet from a fiction movie. Biologists and engineers will have ONE working in just a few years, because the tool that makes it possible, a genetic microarray known as the "DNA chip ", already exists. Able to scrutinize tens of thousands of genes at once, the DNA chip's astonishing abilities are astounding biologists. "Using these chips, people can in one afternoon confirm work that takes several years using conventional gene-sequencing processes". The chips aren't just about increased speed. Using them, researchers can do things that were previously almost impossible, such as, uncovering the genetic machinations behind the complex biochemistry of organisms. For example, with a yeast cell,......
