DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Prions responsible for BSE can survive in new host environment

Scientists from the Florida campus of The Scripps Research Institute have shown that prions, bits of infectious protein that can cause fatal neurodegenerative disease such as bovine spongiform encephalopathy or "mad cow disease," have the ability to adapt to survive in a new host environment.

Genetic biomarker linked to increased risk for breast cancer found in 'junk' DNA

A new genetic biomarker that indicates an increased risk for developing breast cancer can be found in an individual's "junk" (non-coding) DNA, according to a new study featuring work from researchers at the Virginia Bioinformatics Institute (VBI) at Virginia Tech and their colleagues.

PEG-Prom encased nanoparticle aids in cancer detection and treatment

In a proof of principal study in mice, scientists at Johns Hopkins and the Virginia Commonwealth University have shown that a set of genetic instructions encased in a nanoparticle can be used as an "ignition switch" to rev up gene activity that aids cancer detection and treatment.

BPA exposure reduces quality of womens' eggs retrieved for IVF

A small-scale University of California, San Francisco-led study has identified the first evidence in humans that exposure to bisphenol A (BPA) may compromise the quality of a woman's eggs retrieved for in vitro fertilization (IVF). As blood levels of BPA in the women studied doubled, the percentage of eggs that fertilized normally declined by 50 percent, according to the research team.
