KU Leuven A team of Belgian biologists led by researchers at KU Leuven has provided the first genetic evidence that rapid evolution can help non-native plant species spread in new environments. Using samples of centuries-old herbaria and DNA analysis, the researchers reconstructed the genetic adaptations undergone by the Pyrenean rocket prior to its rapid spread in Belgium. The Pyrenean rocket (Sisymbrium austriacum subsp. Chrysanthum) is a plant that grows in the mountains of southern...

DOE/Joint Genome Institute In the Lewis Carroll classic, Through the Looking Glass, Humpty Dumpty states, "When I use a word, it means just what I choose it to mean—neither more nor less." In turn, Alice (of Wonderland fame) says, "The question is, whether you can make words mean so many different things." All organisms on Earth use a genetic code, which is the language in which the building plans for proteins are specified in their DNA. It has long been assumed that there is only one...

Genetics Also Play A Role In Mate Selection

Brett Smith for redOrbit.com - Your Universe Online Many of us might think, by looking at friends and family, that people tend to marry someone similar to them – and a new study in the journal Proceedings of the National Academy of Sciences (PNAS) has found that these similarities often go beyond more than skin deep. According to the study, individuals and their spouses tend to be more genetically similar than they are to randomly chosen people. While previous studies have found that...

Genetically Altering E. Coli With New Semi-Synthetic DNA Base Pairs
2014-05-08 07:24:29

Lawrence LeBlond for redOrbit.com - Your Universe Online It is well-known that all life on Earth is made up of two base pairs, known as A-T (adenine–thymine) and C-G (cytosine–guanine), which form the standard double helix DNA strand. But that could all change now that researchers at The Scripps Research Institute (TSRI) have engineered a bacterium to contain an extra pair of DNA “letters” that are not found anywhere else in nature. The cells of this bacterium are also able to...

Each time a human cell divides, it must first make a copy of its 46 chromosomes to serve as an instruction manual for the new cell. Normally, this process goes off without a hitch. But from time to time, the information isn't copied and collated properly, leaving gaps or breaks that the cell has to carefully combine back together. Researchers have long recognized that some regions of the chromosome,called "fragile sites," are more prone to breakage and can be a breeding ground for human...

Recent research has shown that tiny fragments of DNA circulating in a person's blood can allow scientists to monitor cancer growth and even get a sneak peek into a developing fetus' gene sequences. But isolating and sequencing these bits of genetic material renders little insight into how that DNA is used to generate the dizzying array of cells, tissues and biological processes that define our bodies and our lives. Now researchers at Stanford University have moved beyond relying on the...

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...

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...
