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...

Atlas Of Human Gene Activity
2014-03-28 05:31:57

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...

This week in Molecular Biology and Evolution Male bears are seemingly always on the prowl, roaming much greater distances than females, particularly for mating. For bear evolution, studying the paternally inherited Y chromosome is therefore a rich source to trace both the geographic dispersal and genetic differences between bear species. This new study is particularly important, because a large part of our current knowledge about range-wide population structuring in mammals relies on...

DNA Could Revolutionize Facial Reconstruction
2014-03-24 04:39:45

redOrbit Staff & Wire Reports - Your Universe Online While scientists can already use DNA to determine an unknown person’s gender or ancestry, new research appearing in the March 20 issue of PLOS Genetics suggests that it will soon be able to help identify his or her actual facial features. According to the Daily Mail, the researchers examined the genes that appeared to correlate with facial structures, as well as the facial structures of the people possessing those genes. They...

Identigene DNA Paternity Test Brings Family Together—Both Parties ‘Thrilled’ About New Family Unit Salt Lake City, UT (PRWEB) March 19, 2014 Identigene customer, LaTeasha Carter, understood the importance of having a father in her own childhood and wanted the same for her grandson. She identified the man she believed was her grandson’s father, becoming convinced after seeing his baby pictures on Facebook. An at-home DNA paternity test kit from Identigene later confirmed he was...

Polynesian Chickens May Have Flown The Coop, But They Didn't Make It To South America: Study
2014-03-19 11:07:14

Lawrence LeBlond for redOrbit.com - Your Universe Online It is commonly agreed in the scientific community that Polynesians expanded their culture throughout the South Pacific some 3,000 years ago and later arrived in places like Tahiti and Hawaii. But did the Polynesians make it all the way to South America? And if they did, did they beat Columbus? New evidence paints a pretty clear picture that Polynesians were in fact not the first to arrive in South America, and maybe never made 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...
