From time to time, living cells will accidentally make an extra copy of a gene during the normal replication process. Throughout the history of life, evolution has molded some of these seemingly superfluous genes into a source of genetic novelty, adaptation and diversity. A new study shows one way that some duplicate genes could have long-ago escaped elimination from the genome, leading to the genetic innovation seen in modern life. Researchers have shown that a process called DNA...

Some three billion base pairs make up the human genome—the floor plan of life. In 2003, the Human Genome Project announced the successful decryption of this code, a tour de force that continues to supply a stream of insights relevant to human health and disease. Nevertheless, the primary actors in virtually all life processes are the proteins coded for by DNA sequences known as genes. For a broad spectrum of diseases, proteins can yield far more compelling revelations than may be gleaned...

The long and the short of telomeres In captivity, grey parrots are often kept in social isolation, which can have detrimental effects on their health and wellbeing. So far there have not been any studies on the effects of long term social isolation from conspecifics on cellular aging. Telomeres shorten with each cell division, and once a critical length is reached, cells are unable to divide further (a stage known as 'replicative senescence'). Although cellular senescence is a useful...

Non-coding DNA sequences found in all plants may have undiscovered roles in basic plant development and response to the environment DNA is the molecule that encodes the genetic instructions enabling a cell to produce the thousands of proteins it typically needs. The linear sequence of the A, T, C, and G bases in what is called coding DNA determines the particular protein that a short segment of DNA, known as a gene, will encode. But in many organisms, there is much more DNA in a cell than...

Researchers have pinpointed a new mechanism of how natural variation in our DNA alters an individual's risk for developing heart disease by interfering with the ability of a developmental gene to interact with a specialized type of RNA. This work expands on previous work identifying the "hidden" causes of complex disease risk, with the goal of unlocking new pathways and potential drug targets for cardiovascular disease. This latest study led by Thomas Quertermous, MD at Stanford University...

Lee Rannals for redOrbit.com - Your Universe Online Scientists have created the first detailed map of the way human genes work throughout major cells and tissues. Researchers working on the FANTOM5 project created a map that shows how a network of switches built within our DNA controls where and when our genes turn off and on. The three-year project included more than 250 scientists in over 20 countries and regions. "The FANTOM5 project is a tremendous achievement. To use the analogy...

Brief Introduction To DNA Probes

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...

Bacillus subtilis, also known as hay bacillus or grass bacillus, is a Gram-positive, catalase-positive bacterium commonly found in soil. It is rod-shaped and a member of the genus Bacillus. It also has the ability to form a tough, protective endospore, allowing the organism to tolerate extreme environmental conditions. B. subtilis has historically been classified as an obligate aerobe, though recent research has proven this to not be strictly correct. It is not a human pathogen although...

  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
