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

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...
