Rapid movements of living biomolecules visualised
Dutch researcher Chris Molenaar has made the rapid movements of proteins, DNA and RNA molecules visible in living cells. With this technique researchers can study the dynamics of biomolecules in their natural environment. Molenaar developed a method which makes it possible to follow the movements... view more (2003-06-24)

Molecular 'signature' protects cells from viruses
Every cell constantly produces a whole arsenal of proteins. The instruction what is to be built comes from the cell nucleus: this is where the DNA is stored, the heredity molecule in which, so to speak, the construction blueprints for all cellular proteins are stored.   view more (2006-10-13)

RNA Toxicity Contributes to Neurodegenerative Disease, University of Pennsylvania Scientists Say
Expanding on prior research performed at the University of Pennsylvania, Penn biologists have determined that faulty RNA, the blueprint that creates mutated, toxic proteins, contributes to a family of neurodegenerative disorders in humans.   view more (2008-05-22)

Small RNA plays parallel roles in bacterial metabolism
They are often overlooked, and were once thought to be too small to contribute much to major cellular processes, but in recent years the study of small ribonucleic acids (sRNA) has gained momentum.   view more (2007-11-30)

Pol3 mutation disrupts organ growth
The cellular mechanism that turns DNA into all of the thousands of proteins that make up a human body is itself both intricate and interesting.   view more (2007-11-27)

Properties of Unusual Virus Revealed in Researchers
A team of researchers from Penn State University and the University of Chicago has uncovered clues that may explain how and why a particular virus, called N4, injects an unusual substance -- an RNA polymerase protein -- into an E. coli bacterial cell. The results, which are published in the current... view more (2008-12-09)

Brain tissue reveals possible genetic trigger for schizophrenia
A study led by scientists from the University of North Carolina at Chapel Hill may have identified a molecular mechanism involved in the development of schizophrenia.   view more (2007-03-29)

New method provides panoramic view of protein-RNA interactions in living cells
DNA, it has turned out, isn't all it was cracked up to be. In recent years we learned that the molecule of life, the discovery of the 20th century, did not -- could not -- by itself explain the huge differences in complexity between a human and a worm.   view more (2008-11-03)

Molecular steps involved in the creation of gene-silencing MicroRNAs identified
First discovered only a few brief years ago, microRNAs are small, remarkably powerful molecules that appear to play a pivotal role in gene silencing, one of the body's main strategies for regulating its genome. A scant 22 nucleotides in length, miRNAs appear to work by binding to and somehow... view more (2005-06-23)

Scientists discover small RNAs that regulate gene expression and protect the genome
RNA is best known as a working copy of the DNA sequence of genes. In this role, it's a carrier of the genes' instructions to the cell, which manufactures proteins according to information in the RNA molecule.   view more (2008-05-14)

Molecular sleuths track evolution through the ribosome
A new study of the ribosome, the cell's protein-building machinery, sheds light on the oldest branches of the evolutionary tree of life and suggests that differences in ribosomal structure between the three main branches of that tree are "molecular fossils" of the early evolution of... view more (2008-08-19)

Rules to Target RNA Are Focus of Research
Once described as DNA's less-famous chemical cousin, RNA, or ribonucleic acid, recently has moved to center stage.   view more (2005-12-19)

Towards a unified model of transcription termination
Dr. David Bentley (University of Colorado School of Medicine) and colleagues have developed a new, unified model for transcription termination by RNA Poymerase II.   view more (2006-04-07)

RNA enzyme structure offers a glimpse into the origins of life
Researchers at the University of California, Santa Cruz, have determined the three-dimensional structure of an RNA enzyme, or "ribozyme," that carries out a fundamental reaction required to make new RNA molecules.   view more (2007-03-16)

Oxford Improves Production Method for Interfering RNA
Researchers at Oxford University's Department of Biochemistry have developed methods for making RNA duplexes and single-stranded RNAs of desired length and sequence. This exciting technology is most applicable to commercial RNA providers and companies with large in-house requirements for RNA... view more (2003-04-29)

Toxic molecule may cause most common type of muscular dystrophy
Doctors at the University of Virginia Health System have shown for the first time that getting rid of poisonous RNA (ribonucleic acid) in muscle cells can reverse myotonic dystrophy, the most common type of muscular dystrophy in adults.   view more (2006-08-25)

Evolution of fruit size in tomato
Domesticated tomatoes can be up to 1000 times larger than their wild relatives. How did they get so big? In general, domesticated food plants have larger fruits, heads of grain, tubers, etc, because this is one of the characteristics that early hunter-gatherers chose when foraging for food.   view more (2008-06-30)

Gene silencing technique offers new strategy for treating, curing disease
A new technique aimed at directly controlling the expression of genes by turning them on or off at the DNA level could lead to drugs for the treatment or cure of many diseases, say researchers at UT Southwestern Medical Center.   view more (2005-08-01)

Accelerated evolution converts RNA enzyme to DNA enzyme in vitro
This 'evolutionary conversion' provides a modern-day snapshot of how life as we understand it may have first evolved out of the earliest primordial mix of RNA-like molecules-sometimes referred to as the "pre-RNA world"-into a more complex form of RNA-based life (or the "RNA... view more (2006-03-28)

'Superdense' coding gets denser
The record for the most amount of information sent by a single photon has been broken by researchers at the University of Illinois. Using the direction of "wiggling" and "twisting" of a pair of hyper-entangled photons, they have beaten a fundamental limit on the channel capacity... view more (2008-03-25)

Penn study finds a new role for RNA in human immune response
Researchers at the University of Pennsylvania School of Medicine have published the first study to test the role of RNA chemical modifications on immunity.   view more (2005-08-24)

Yale scientists visualize the machinery of mRNA splicing
Recent research at Yale provided a glimpse of the ancient mechanism that helped diversify our genomes; it illuminated a relationship between gene processing in humans and the most primitive organisms by creating the first crystal structure of a crucial self-splicing region of RNA.   view more (2008-04-07)

New compound effectively treats fungal infections
A new mechanism to attack hard-to-treat fungal infections has been revealed by scientists from the biotech company Anacor Pharmaceuticals Inc., California, and the European Molecular Biology Laboratory [EMBL] outstation in Grenoble, France.   view more (2007-06-25)

Plant polymerases IV and V are special forms of Polymerase II
It's a little like finding out that Superman is actually Clark Kent. A team of biologists at Washington University in St. Louis has discovered that two vital cellular components, nuclear RNA Polymerases IV and V (Pol IV and V), found only in plants, are actually specialized forms of RNA Polymerase... view more (2009-01-07)

RNA found in the cellular centrosome of surf clams
