Latest Helices Stories
Nanoscale "cages" made from strands of DNA can encapsulate small-molecule drugs and release them in response to a specific stimulus.
Building on earlier work exploring the complex choreography by which intricate cellular proteins interact with and copy DNA prior to cell division, scientists at the U.S. Department of Energy's Brookhaven National Laboratory and collaborators have captured a key step-molecular images showing how the enzyme that unwinds the DNA double helix gets drawn to and wrapped around its target.
DNA Services of America, founded by entrepreneur Jeffrey A.
The Genomic Instability Group led by researcher Óscar Fernández-Capetillo at the Spanish National Cancer Research Centre (CNIO), has for the first time obtained a panoramic photo of the proteins that take part in human DNA division, a process known as replication.
Scientists have revealed how a bacterial enzyme has evolved an energy-efficient method to move long distances along DNA.
A research team from NPL and the University of Edinburgh have invented a new way to zip and unzip DNA strands using electrochemistry.
A handwritten letter sent from one of the scientists responsible for discovering the structure of DNA will be auctioned off next month in New York City, according to various media reports.
In a new discovery that represents a major step in solving a critical design challenge, Arizona State University Professor Hao Yan has led a research team to produce a wide variety of 2-D and 3-D structures that push the boundaries of the burgeoning field of DNA nanotechnology.
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.
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...
- In dressmaking, straps running from the belt in front over the shoulders to the belt in the back, with more or less elaboration of trimming and outline. They usually broaden at the shoulder and narrow toward the waist.
