Latest DNA Stories
While the legend of Bigfoot is quite popular, popular enough for its own reality television show, a team of international scientists has tested 30 archival hair samples linked to the legendary beast and concluded that none of them can be attributed to any such creature.

Nucleic acid isolation and purification is often the first step in most molecular biology techniques like cloning, sequencing, polymerase chain reaction (PCR), and others.
LAFAYETTE, La., June 23, 2014 /PRNewswire-iReach/ -- DNA Services of America, a leader in DNA-based testing services within communities across America, announced today that last month marked

Nanopores may one day lead a revolution in DNA sequencing. By sliding DNA molecules one at a time through tiny holes in a thin membrane, it may be possible to decode long stretches of DNA at lightning speeds.
The subseafloor is home to over 1/3 of the bacteria on the planet, but up until recently it was unclear if this huge microbial biosphere was alive and dividing.

Twelve years ago, UNC School of Medicine researcher Brian Strahl, PhD, found that a protein called Set2 plays a role in how yeast genes are expressed – specifically how DNA gets transcribed into messenger RNA.
So-called silent DNA mutations earned their title because, according to the fundamental rules of biology, they should be inconsequential.
DNA probes help scientists to detect a specific gene in a long DNA sequence. According to Dr. Michael A. Pfaller, DNA probes are “single-stranded pieces of nucleic acid, labeled with a specific tracer (isotope, enzyme, or chromophore), that will hydrogen bond (hybridize) with complementary single-stranded pieces of DNA (or RNA) under the appropriate conditions of pH, temperature, and iconic strength.” The Foundation for Genomics and Population Health website has a helpful video about...
Bacillus subtilis, also known as hay bacillus or grass bacillus, is a Gram-positive, catalase-positive bacterium commonly found in soil. It is rod-shaped and a member of the genus Bacillus. It also has the ability to form a tough, protective endospore, allowing the organism to tolerate extreme environmental conditions. B. subtilis has historically been classified as an obligate aerobe, though recent research has proven this to not be strictly correct. It is not a human pathogen although...
