It focused narrowly on areas in and around active genes, ignoring the 98.5% of genomic material known as "junk DNA." This process pinpointed 25, 000 genetic landmarks called SNPS (single nucleotide polymorphisms, or "snips"), places where a single dna letter varies from one person to the next.
This year's top performer for the Invesco fund is Orchid BioScience, which makes biochips--microchips integrated with DNA molecules for use in genomic research.
