New cutting-edge research report “DNA and RNA Isolation Techniques: Market Developments, Growth Areas and Opportunities” worked out by Biopharm Reports has been recently published by Market Publishers Ltd. London, UK (PRWEB) October 16, 2013 Nowadays, DNA and RNA isolation procedures form a backbone of the molecular biology field. For a slew of applications beginning from fundamental research and finishing with routine diagnostics and therapeutic decision-making, these molecules are...

The kinds of traits that show genealogical relationships between species are often minute and easily overlooked. Dr. Neil Snow, a botanist at Pittsburg State University, published a paper in 1996 that included observations of some odd-shaped hairs on three species of grass native to Africa. Their odd shape stems from distinctly swollen tips that are then pinched into a small party-hat structure at the very apex. "A tongue-twisting technical term for that shape is 'clavicorniculate', but...

STONYBROOK, N.Y., Oct. 7, 2013 /PRNewswire/ -- London's police plan is to slash crime in some of the most hardscrabble neighborhoods in the city while cutting costs and while redeploying anti-crime resources. That's a nice trick, say observers who are watching how law enforcement will react as the capital's law enforcement budget has been trimmed even while the pressure to keep London safe is as high as ever. Fortunately, there's an app for that. Recently, London's Metropolitan...

Researchers find nanostructures made of DNA strands can encapsulate, release small-molecule drugs Nanoscale "cages" made from strands of DNA can encapsulate small-molecule drugs and release them in response to a specific stimulus, McGill University researchers report in a new study. The research, published online Sept. 1 in Nature Chemistry, marks a step toward the use of biological nanostructures to deliver drugs to diseased cells in patients. The findings could also open up new...

New Details Of Biochemical Interactions Necessary For Cell Division Identified
2013-07-15 12:05:33

DOE/Brookhaven National Laboratory 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. Details of the research, published in the journal Nature Structural...

A study led by Oscar Fernandez-Capetillo has deciphered the components of the machinery that duplicates DNA, the replisome, on which most chemotherapeutic agents currently act 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. The research article,...

Scientists have revealed how a bacterial enzyme has evolved an energy-efficient method to move long distances along DNA. The findings, published in Science, present further insight into the coupling of chemical and mechanical energy by a class of enzymes called helicases, a widely-distributed group of proteins, which in human cells are implicated in some cancers. The new helicase mechanism discovered in this study, led by researchers from the University of Bristol and the Technische...

A research team from NPL and the University of Edinburgh have invented a new way to zip and unzip DNA strands using electrochemistry. The DNA double helix has been one of the most recognizable structures in science ever since it was first described by Watson and Crick almost 60 years ago (paper published in Nature in 25 April 1953). The binding and unbinding mechanism of DNA strands is vital to natural biological processes and to the polymerase chain reactions used in biotechnology to copy...

DNA Discoverer's Letter To Be Auctioned Off
2013-03-25 05:26:50

redOrbit Staff & Wire Reports - Your Universe Online 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 the letter, which was written on March 19, 1953, British molecular biologist and biophysicist Francis Crick explains to his then-12-year-old son Michael how he and colleague James Watson were able to create a model for the genetic...

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...
