An iconic photograph (http://img.timeinc.net/time/80days/images/530228.jpg) of Nobel laureates Drs. Francis Crick and James Watson show the pair discussing with a rigid model of the famous double helix.The interaction represented produced the famous explanation of the structure of DNA, but the model pictured is a stiff snapshot of idealized DNA. As researchers from Baylor College of Medicine (www.bcm.edu) and the University of Houston (www.uh.edu) note in a report that appears online in the...

A team of Penn State scientists has shed light on the processes that lead to certain human DNA mutations that are implicated in hundreds of inherited diseases such as tuberous sclerosis and neurofibromatosis type 1. The results one day could influence the way couples who seek to have children receive genetic counseling. The team, led by Kateryna Makova, an associate professor of biology, also includes Erika Kvikstad, a graduate student in the Department of Biology, and Francesca Chiaromonte,...

The genomes or DNA of microbes contain defined DNA patterns called genome signatures. Such signatures may be used to establish relationships and to search for DNA from viruses or other organisms in the microbes' genomes. Foreign DNA in bacteria has often been associated with disease-causing abilities.In his doctorate, Jon Bohlin studied methods for examining the genome signatures of microbes. Since foreign DNA in the genomes of bacteria often give the bacteria disease-causing abilities, part...

Biomatrica's SampleMatrix(R) Technology Used in Sustainability Initiative SAN DIEGO, June 3 /PRNewswire/ -- A major U.S. university could cut its electricity usage by 40 million kilowatt-hours (kWh), reduce its carbon footprint by an estimated 18,000 metric tons and save $16 million in operating costs over the next 10 years by transferring biological samples from frozen storage to room-temperature storage technology, according to the results of a pilot project released by Biomatrica(R)...

By combining the art of origami with nanotechnology, Dana-Farber Cancer Institute researchers have folded sheets of DNA into multilayered objects with dimensions thousands of times smaller than the thickness of a human hair. These tiny structures could be forerunners of custom-made biomedical nanodevices such as "smart" delivery vehicles that would sneak drugs into patients' cells, where they would dump their cargo on a specific molecular target.While creation of structures from single layers...

A U.S. genetic researcher says she believes there's a market among hobbyists who'd want to buy equipment to test their own DNA sequences. Katherine Aull, a 23-year-old graduate of the Massachusetts Institute of Technology, is creating a start-up biotech company in her Cambridge, Mass., apartment to tap what she and others believe may be a market among non-scientists who would want to use home computers to probe the traits of their own DNA, The Boston Globe reported Monday. The newspaper said...

HOUSTON, April 8 /PRNewswire/ -- LaserGen, Inc., a DNA sequencing technology company, announced a definitive agreement in which SeqWright Inc. will make an equity investment in the company. Prompting its decision was LaserGen's recently revealed plans to commercialize its novel reversible terminator chemistry, Lightning Terminators(TM), for next-generation sequencing applications. The company anticipates bringing its chemistry as reagent kits to the market as early as 2010, by forming...

Chemists at New York University and Harvard University have created a bipedal, autonomous DNA "walker" that can mimic a cell's transportation system. The device, which marks a step toward more complex synthetic molecular motor systems, is described in the most recent issue of the journal Science. For a video demonstration of the walker, go to http://www.nyu.edu/public.affairs/videos/qtime/biped_movie.mov.Two fundamental components of life's building blocks are DNA, which encodes instructions...

A U.S. scientist and his colleagues have described the design of a new type of DNA with 12 chemical letters instead of the usual four. Researchers, led by Steven Benner of the Foundation for Applied Molecular Evolution in Gainesville, Fla., said their artificial genetic system already is helping to usher in the era of personalized medicine. The scientists said their research might also shed light on how life arose on Earth, by producing a self-sustaining molecule capable of Darwinian...

Brief Introduction To DNA Probes
2014-01-12 00:00:00

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...
