A new discovery may make it easier for scientists to manipulate DNA in the laboratory, a paper from the University of Illinois at Urbana Champagne said. Three scientists at the university discovered catalytic DNA known as deoxyribozymes that can cleave DNA strands to become catalysts for research.
Our genome is constantly under attack from things like UV light and toxins, which can damage or even break DNA strands and ultimately lead to cancer and other diseases.
Scientists at the Technische Universitaet Muenchen (TUM) and Harvard University have thrown the lid off a new toolbox for building nanoscale structures out of DNA, with complex twisting and curving shapes.
FORT WORTH, Texas, Aug. 4 /PRNewswire-USNewswire/ -- Of the 600,000-800,000 people trafficked across international borders each year, 50 percent are under 17. It is estimated that by 2010, human trafficking will be the No. 1 crime worldwide.
Numerous pathogens contain an 'internal time bomb', a deadly mechanism that can be used against them.
The Health Sciences Center of the University of North Texas and the University of Granada collaborate in DNA â€“ Prokids, an international project aimed at fighting against traffic in children using the lasts techniques in genetic identification of human beings.
By manipulating individual atoms in DNA and forming unique molecules, a Georgia State University researcher hopes to open new avenues in research towards better understanding the mechanisms of DNA replication and transcription, and perhaps leading to new treatments for diseases.
An iconic photograph (http://img.timeinc.net/time/80days/images/530228.jpg) of Nobel laureates Drs. Francis Crick and James Watson show the pair discussing with a rigid model of the famous double helix.
A team of Penn State scientists has shed light on the processes that lead to certain human DNA mutations that are implicated in hundreds of inherited diseases such as tuberous sclerosis and neurofibromatosis type 1.
The genomes or DNA of microbes contain defined DNA patterns called genome signatures. Such signatures may be used to establish relationships and to search for DNA from viruses or other organisms in the microbes' genomes.
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...
