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.
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.
Researchers at Harvard University have developed a new spring that is soft when pulled gently and stiff when pulled strongly – all from studying a cucumber.
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.
DNA holds the genetic code for all sorts of biological molecules and traits.
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...
