Human Genome Found To Contain Quadruple Helix DNA Strands
2013-01-21 05:09:41

On the 60th anniversary of the publication of the paper describing the double-helix structure of DNA, researchers from Cambridge University reportedly have proven the existence of four-stranded “quadruple helix” DNA structures within the human genome.

Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, with collaborators from Harvard University, the University of Madrid, Princeton University, and the University of Zurich, have discovered a new mechanism that may alter principle understandings of molecular interactions within a cell’s nucleus.

An international team of scientists have shown at an unprecedented level of detail how cells prioritize the repair of genes containing potentially dangerous damage.

Secrets Of Genetic Switch Unraveled

When an invading bacterium or virus starts rummaging through the contents of a cell nucleus, using proteins like tiny hands to rearrange the host’s DNA strands, it can alter the host’s biological course.

Cucumber Inspires New Bio-Inspired Twistless Spring

In a discovery that defies the popular meaning of the word "wire," scientists have found that Mother Nature uses DNA as a wire to detect the constantly occurring genetic damage and mistakes that ― if left unrepaired ― can result in diseases like cancer and underpin the physical and mental decline of aging.

In a new study, UT Dallas researchers outline how they used fluorescent molecules to “tag” DNA and monitor a process called DNA looping, a natural biological mechanism involved in rearranging genetic material in some types of cells.

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...

mitraille
  • Small missiles, especially grape, canister, fragments of iron, and the like, when fired, as upon an enemy at close quarters.
  • To fire mitraille at.
The word 'mitraille' comes from the Old French 'mitaille', meaning 'small coins', sometimes used to mean 'scrap iron'.
