A novel study from Karolinska Institutet has deepened the understanding of how chromosome replication, one of life's most fundamental processes, works. In a long term perspective these results could eventually lead to novel cancer therapies. The study is presented in the prestigious scientific journal Nature. By studying DNA replication in yeast cells, researchers at Karolinska Institutet have discovered that a protein complex (Smc5/6) helps to release torsional stress created in the DNA...

Scientists have published results that will forever change the way researchers view the interplay between gene expression, DNA replication and the prevention of DNA damage. DNA damage, if not kept in check, can lead to many problems including cancers. Researchers, funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and the Wellcome Trust and working at The University of Nottingham, have shown that the process of replication is even riskier than originally thought....

DNA, that marvelous, twisty molecule of life, has an alter ego, research at the University of Michigan and the University of California, Irvine reveals. On rare occasions, its building blocks "rock and roll," deforming the familiar double helix into a different shape. "We show that the simple DNA double helix exists in an alternative form"”for one percent of the time"”and that this alternative form is functional," said Hashim M. Al-Hashimi, who is the Robert L. Kuczkowski...

Duke University bioengineers have developed a new method for rapidly producing an almost unlimited variety of man-made DNA sequences. These novel sequences of recombinant DNA are used to produce repetitive proteins to create new types of drugs and bioengineered tissues. Current methods for producing these DNA sequences are slow or not robust, the researchers said, which has hindered the development of these increasingly important new classes of protein-based polymers. Researchers have already...

Using a new experimental test structure, biophysicists at JILA have unraveled part of a 15-year mystery in the mechanics of DNA"”just how the molecule manages to suddenly extend to almost twice its normal length. The new test structure should support research on DNA elasticity as a standard for tiny forces and help refine studies of how drugs and other substances bind to DNA. In a new paper in the Journal of the American Chemical Society,* JILA scientists disprove a leading explanation...

New technology providing the first view of DNA damage throughout the entire human genome developed by Cardiff University scientists could offer a valuable new insight into the development and treatment of conditions like cancer. Professor Ray Waters, Dr Simon Reed and Dr Yumin Teng from Cardiff University's Department of Genetics, Haematology and Pathology have developed a unique way of measuring DNA damage frequency using tiny microarrays. Using the new method Cardiff scientists can, for the...

AKRON, Ohio, Jan. 4, 2011 /PRNewswire/ -- A new method of child and maternal nutrition could prevent a specific type of genetic damage that would otherwise occur in up to 160 million brain cells in each person over their lifetime. Preventing this genetic damage could have significant implications related to aging and cancer. Most people are unaware that every type of food currently eaten is measurably contaminated with a radioactive material from the air known as carbon-14, or radiocarbon....

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...
