Using state-of-the-art technology, scientists at the Novo Nordisk Foundation Center for Protein Research at the University of Copenhagen and their international collaborators have successfully obtained "molecular snapshots" of tens of thousands processes involved in DNA damage repair. On a daily basis this restoration keeps cells healthy and prevents the development of cancer. The results of this study will help unravel exactly how cells repair their broken DNA, how chemotherapy affects...

So what is it that gives NY Knicks Jeremy Lin his unique competitive edge? Greg Herzog, a former sub four minute miler and conditioning specialist in New York City has worked with competitive athletes, as well as individuals from the ages 5-94, and has made studying human performance his life´s work. This extensive experience led to the development of “AXIS CORE®”, a mathematical equation to predict and change behavior, as well as a Quantum Reaction Theory: COLOR CODING...

The search for a solid answer on whether DNA can be reprogrammed or influenced through frequencies and words may have been answered based on a recent study by noted Russian biophysicist and molecular biologist Pjotr Garjajev and supporting article posted at BeWellBuzz.com. Las Vegas, NV (PRWEB) February 23, 2012 The search for a solid answer on whether DNA can be reprogrammed or influenced through frequencies and words may have been answered based on a recent study by noted Russian...

Molecule is important step along the path to someday creating drugs that can go after rogue DNA directly Chemists at The University of Texas at Austin have created a molecule that's so good at tangling itself inside the double helix of a DNA sequence that it can stay there for up to 16 days before the DNA liberates itself, much longer than any other molecule reported. It's an important step along the path to someday creating drugs that can go after rogue DNA directly. Such drugs would...

A research group in the Faculty of Medicine & Dentistry at the University of Alberta is hoping its latest discovery could one day be used to develop new therapies that target certain types of cancers. The discovery by Mark Glover, his graduate student Zahra Havali-Shahriari and post-doctoral fellow Nicolas Coquelle has shed light on what happens in cells when DNA is damaged. They solved the structure of a DNA repair enzyme called polynucleotide kinase/phosphatase, or PNKP. This allows...

It's been more than 50 years since James Watson and Francis Crick showed that DNA is a double helix of two strands that complement each other. But how does a short piece of DNA find its match, out of the millions of 'letters' in even a small genome? New work by researchers at the University of California, Davis, handling and observing single molecules of DNA, shows how it's done. The results are published online Feb. 8 by the journal Nature. Defects in DNA repair and copying are strongly...

New research published in BioMed Central's open access journal Cell & Bioscience is the first to show that left-handed Z-DNA, normally only found at sites where DNA is being copied, can also form on nucleosomes. The structure of DNA which provides the blueprint for life has famously been described as a double helix. To save space inside the nucleus, DNA is tightly wound around proteins to form nucleosomes which are then further wound and compacted into chromatin, which is further...

A novel technique has been developed and demonstrated at Penn State University to map the proteins that read and regulate chromosomes -- the string-like structures inside cells that carry genes. The specific order in which these proteins attach DNA-containing nucleosomes along the chromosome determines whether a brain cell, a liver cell, or a cancer cell is formed. Until now, it has been exceedingly difficult to determine exactly where such proteins bind to the chromosome, and therefore how...

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...

Word of the Day
caparison
  • A cloth or covering, more or less ornamented, laid over the saddle or furniture of a horse, especially of a sumpter-horse or horse of state.
  • Clothing, especially sumptuous clothing; equipment; outfit.
  • To cover with a caparison, as a horse.
  • To dress sumptuously; adorn with rich dress.
This word ultimately comes from the Medieval Latin 'cappa,' cloak.
