Duke University bioengineers have developed a new method for rapidly producing an almost unlimited variety of man-made DNA sequences. These novel sequences of recombinant DNA are used to produce repetitive proteins to create new types of drugs and bioengineered tissues. Current methods for producing these DNA sequences are slow or not robust, the researchers said, which has hindered the development of these increasingly important new classes of protein-based polymers. Researchers have already...

Using a new experimental test structure, biophysicists at JILA have unraveled part of a 15-year mystery in the mechanics of DNA"”just how the molecule manages to suddenly extend to almost twice its normal length. The new test structure should support research on DNA elasticity as a standard for tiny forces and help refine studies of how drugs and other substances bind to DNA. In a new paper in the Journal of the American Chemical Society,* JILA scientists disprove a leading explanation...

New technology providing the first view of DNA damage throughout the entire human genome developed by Cardiff University scientists could offer a valuable new insight into the development and treatment of conditions like cancer. Professor Ray Waters, Dr Simon Reed and Dr Yumin Teng from Cardiff University's Department of Genetics, Haematology and Pathology have developed a unique way of measuring DNA damage frequency using tiny microarrays. Using the new method Cardiff scientists can, for the...

AKRON, Ohio, Jan. 4, 2011 /PRNewswire/ -- A new method of child and maternal nutrition could prevent a specific type of genetic damage that would otherwise occur in up to 160 million brain cells in each person over their lifetime. Preventing this genetic damage could have significant implications related to aging and cancer. Most people are unaware that every type of food currently eaten is measurably contaminated with a radioactive material from the air known as carbon-14, or radiocarbon....

Graduate student Markita Landry describes her research, learning experiences and cultural adjustment in Japan as part of NSF's EAPSI program Proteins are able to identify a tiny DNA target--usually only a few base pairs long--among thousands of non-targeted base pairs. I study how that happens using high resolution, optical traps. And, to help advance my research for my doctoral thesis, I spent a summer doing research in Toshio Yanagida's laboratory in Osaka, Japan, as part of NSF's East Asia...

Biologists at the University of California, San Diego have found another member in a new class of cellular motor proteins that rewind and seal together sections of the double-stranded DNA molecule that occasionally but perilously become unwound. Their discovery, which provides a promising new avenue for the development of drugs that kill cancer cells, is detailed in a paper published in this week's early online edition of the Proceedings of the National Academy of Sciences. The same...

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...
