Researchers Shed Light on Evolution of Gene Regulation
Scientists at Penn State have shed light on some of the processes that regulate genes -- such as the processes that ensure that proteins are produced at the correct time, place, and amount in an organism -- and they also have shed light on the evolution of the DNA regions that regulate genes. view more (2008-11-25)
K-State researchers study gene regulation in insects
Susan Brown, an associate professor of biology at Kansas State University, is interested in how evolution generates so much diversity in insects shapes and forms. view more (2006-04-28)
Scientists Uncover Rules for Gene Amplification
Gene amplification plays an important role in causing cancers via activation of oncogenes. view more (2006-06-30)
Mayo Clinic discovers DNA repair as key to Huntington's disease
Mayo Clinic researchers, along with collaborators from the National Institutes of Health (NIH) and University of Oslo, Norway, have discovered that a miscue of the body's genetic repair system may cause Huntington's disease, a fatal condition that affects 30,000 Americans annually by destroying their nervous system. view more (2007-04-23)
A better test to detect DNA for diagnosing diease, investigating crimes
Researchers in Singapore are reporting development of a new electronic sensor that shows promise as a faster, less expensive, and more practical alternative than tests now used to detect DNA. view more (2009-08-27)
Centromeres cross over, a lot
Recombination at centromeres is higher than anywhere else on the chromosome, even though methyltransferases do their best to prevent it, say Jaco et al., as published in the June 16 issue of the Journal of Cell Biology. view more (2008-06-13)
Mysterious snippets of DNA withstand eons of evolution, Stanford study
Small stretches of seemingly useless DNA harbor a big secret, say researchers at the Stanford University School of Medicine. There's one problem: We don't know what it is. view more (2008-10-02)
When Good DNA Goes Bad: Backward DNA leads to DNA breaks associated with leukemia, study finds
When otherwise normal DNA adopts an unusual shape called Z-DNA, it can lead to the kind of genetic instability associated with cancers such as leukemia and lymphoma. view more (2006-02-13)
Scientists discover a genetic code for organizing DNA within the nucleus
DNA - the long, thin molecule that carries our hereditary material - is compressed around protein scaffolding in the cell nucleus into tiny spheres called nucleosomes. view more (2006-07-20)
Cataloging the Structural Variations in Human Genetics
A major new effort to uncover the medium- and large-scale genetic differences between humans may soon reveal DNA sequences that contribute to a wide range of diseases. view more (2007-05-10)
Nanotech tools yield DNA transcription breakthrough
Rutgers researcher Richard H. Ebright and his collaborators have resolved key questions regarding transcription, the fundamental life process that was the subject of the 2006 Nobel Prize in Chemistry. view more (2006-11-17)
Melon research sweetened with DNA sequence
People smell them, thump them and eyeball their shape. But ultimately, it's sweetness and a sense of healthy eating that lands a melon in a shopper's cart. view more (2009-06-29)
Liquid crystal phases of tiny DNA molecules point up new scenario for first life on Earth
A team led by the University of Colorado at Boulder and the University of Milan has discovered some unexpected forms of liquid crystals of ultrashort DNA molecules immersed in water, providing a new scenario for a key step in the emergence of life on Earth. view more (2007-11-26)
DNA repair mechanisms relocate in response to stress
Like doctors making house calls, some DNA repair enzymes can relocate to the part of the cell that needs their help, a collaborative team of scientists at Emory University School of Medicine has found. view more (2009-03-27)
The skeleton: Size matters
Vertebrates have in common a skeleton made of segments, the vertebrae. During development of the embryo, each segment is added in a time dependent manner, from the head-end to the tail-end: the first segments to be added become the vertebrae of the neck, later segments become the vertebrae with ribs and the last ones the vertebra located in the... view more...

Study by Israeli scientists provides insight on how DNA code is turned into instructions for protein construction
A team of scientists from the Hebrew University of Jerusalem and the Weizmann Institute of Science has revealed the structure of a cellular editor that "cuts and pastes" the first draft of RNA straight after it is formed from its DNA template. Many diseases appear to be tied to mistakes in this process, and understanding the workings of... view more... (2004-09-09)

Single nucleotide polymorphisms and forensic genetics, maybe not such a perfect combination
Forensic genetics is the branch of genetics that, through DNA analysis and comparison, deals with the resolution of legal problems such as paternity tests. Recently, it has been proposed that single nucleotide polymorphisms (SNPs) could be used as a new genetic marker in the field eventually even replacing the methods/markers now employed. But in... view more... (2004-10-21)
Ancestral genome of present-day African great apes & humans had burst of DNA sequence duplication
The genome of the evolutionary ancestor of humans and present-day apes underwent a burst of activity in duplicating segments of DNA, according to a study to be published in Nature Feb 12, the 200th anniversary of Charles Darwin's birthday. view more (2009-02-12)
Human DNA repair process recorded in action
A key phase in the repair process of damaged human DNA has been observed and visually recorded by a team of researchers at the University of California, Davis. The recordings provide new information about the role played by a protein known as Rad51, which is linked to breast cancer, in this complex and critical process. view more (2009-01-29)
