...erge May 29, 2000 - With 90% of the human genome
already known and many smaller genomes sequenced in their entirety, a revolution known as bioinformatics is beginning to affect profoundly the whole of biology and medicine. To meet this challenge of the "post-genomic age" which experts say will tra...
