Today, molecular biologists possess the tools to clone, sequence and identify thousands of potentially useful expressed sequence tags (ESTs) and single nucleotide polymorphisms (SNPs).

J Craig Venter has been a molecular-biology pioneer for two decades. After developing expressed sequence tags in the 90s, he led the private effort to map the human genome, publishing the results ...

Comparative genomics is emerging as a powerful approach for assessing the similarities and differences between species. In the September Genome Research Band et al. compare cows and humans to generate ...

Although the vast majority of expressed sequence tags (ESTs) and single nucleotide polymorphisms (SNPs) may never prove to be important medically or agriculturally, some could play an important ...
