EMBL scientists identify a rapid response team that monitors and quickly responds to DNA damageOur 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 have known for a long time that when DNA is damaged, a key enzyme sets off a cellular "Ëœalarm bell' to alert the cell to start the repair process, but until recently little was known about how the cell detects...

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. In the August 7 issue of the journal Science, they report a series of experiments in which they folded DNA, origami-like, into three dimensional objects including a beachball-shaped wireframe capsule just 50 nanometers in diameter."Our goal was to find out whether we could program DNA to...

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. Arthur Eisenberg, Ph.D., professor and chairman of the department of forensic and investigative Genetics and co-director of the UNT Center for Human Identification at the University of North Texas (UNT) Health Science Center, is on a mission to stop...

 Numerous pathogens contain an 'internal time bomb', a deadly mechanism that can be used against them. After years of work, VIB researchers at the Vrije Universiteit Brussel (VUB) were able to determine the structure and operating mechanism of the proteins involved. This clears the road for finding ways to set the clock on this internal time bomb and, hopefully, in the process developing a new class of antibiotics. The research was accepted for publication by top journal Molecular Cell,...

The Health Sciences Center of the University of North Texas and the University of Granada collaborate in DNA "“ Prokids, an international project aimed at fighting against traffic in children using the lasts techniques in genetic identification of human beings. Upon suggestion of the Laboratory of Genetic Identification of the University of Granada, an international project for genetic identification of missing children and their families was set up in 2004. Last May, the project was...

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. Chemistry and chemical biology Professor Zhen Huang and his lab were able for the first time, to manipulate groups of molecules, called methyl and phosphate groups, in DNA that has been altered to contain selenium in...

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.The interaction represented produced the famous explanation of the structure of DNA, but the model pictured is a stiff snapshot of idealized DNA. As researchers from Baylor College of Medicine (www.bcm.edu) and the University of Houston (www.uh.edu) note in a report that appears online in the...

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 results one day could influence the way couples who seek to have children receive genetic counseling. The team, led by Kateryna Makova, an associate professor of biology, also includes Erika Kvikstad, a graduate student in the Department of Biology, and Francesca Chiaromonte,...

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. Foreign DNA in bacteria has often been associated with disease-causing abilities.In his doctorate, Jon Bohlin studied methods for examining the genome signatures of microbes. Since foreign DNA in the genomes of bacteria often give the bacteria disease-causing abilities, part...

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...
