How do microarrays work?
The Virtual Microarray: Version 2.3
Anastasios Koutsos, Alexandra Manaia and Julia Willingale-Theune
Scientists around the world are working on one of the most ambitious projects ever thought up by man: 'The human genome project'. Now that the genome has been sequenced, the new challenge is to work out what the individual genes do, and to do so scientists are designing sophisticated tools. One such tool is the DNA microarray, or DNA chip, which promises to carry the science of understanding genomes to a whole new level. These highly sophisticated tools cannot be reproduced in the school lab, but their underlying concepts can be illustrated in the classroom using 'The Virtual Microarray'.
The virtual microarray brings cutting-edge science into the classroom by simulating the different steps that researchers take in performing microarray experiments and in analyzing their results (Real and Virtual Microarrays: Step by Step).
Although we have tried our best to adjust the examples and illustrations in the 'virtual microarray' to correspond to the procedures in the 'real microarray', on occasions, which are implicitly mentioned, the procedures differ. We have also included a section that contains technical information and suggestions on how to perform the virtual microarray experiment in the classroom.
Finally, you will also find a Reading Club section, where we present and explain original research articles written by scientists who have used the microarray technique to answer important biological questions.
