variation
LSU researcher participates in NIH-funded study ushering in the age of personal genomics
BATON ROUGE — Genetic diseases impact millions around the world each and every day. Complex medical conditions with genetic predispositions, such as hypertension, can also weigh heavily on our lives. Susceptibility to hypertension has many genetic…
Third generation map of human genetic variation published
An international consortium today published a third-generation map of human genetic variation, called the HapMap, which includes data from an additional seven global populations, increasing the total number to 11 populations. The improved resolution…
Scientists find two forms of genetic material chromatin
Biologists have discovered what appear to be fundamental differences in the physical properties of the genetic material known as chromatin. Chromatin packages DNA into cells, and the scientists found the differences between chromatin that packages genes and the chromatin that packages DNA with regulatory or unknown functions. The variation represents a previously unrecognized level of genomic organization and complexity, the scientists report, one that may exist in all cells with nuclei.
