These predictions would then need to be confirmed by experimentation, such as by the use of "gene chips" (microarrays). A microarray consists of a glass chip that has thousands of DNA fragments (taken from the genome) attached at discrete positions [see "Genes on a Chip," The World & I, September 1997, p. 189]. It can be used to identify DNA sequences that code for RNA and proteins.--D.K.D.
