Exploring the Dark Matter of the Genome Sequencing Unravels Secrets in the Complex Heterochromatin of the Fruit Fly.Tomado de la URL http://www.lbl.gov/Science-Articles/Archive/LSD-genome-darkmatter.htmlChris Smith uses the metaphor of dark matter to suggest the significance of heterochromatin. "We don't know what holds the galaxies together, and the same is true of the genome. We're pretty good at understanding how individual genes work, but we don't understand, for example, how the large-------------------scale structure of genomes affects cellular processes. -----We hear too much about the "post-genomic era" — it's underappreciated that we don't understand the genome yet." -------------------------------------------
