As much as half of the human genome is composed of so-called "jumping genes." These DNA sequences can make copies of themselves that are inserted back into the genome at another location, playing a significant functional ...
After a cyclospora outbreak and recalls of imported beef over the summer, a recent Gallup poll found that Americans' confidence in food safety has fallen to a record low, and consumers may be wondering how foodborne illness ...
DNA is not randomly distributed within the nucleus but is packaged with proteins into chromatin, which is precisely folded into complex three-dimensional structures. However, scientists have not fully understood how this ...
Graduate students in Penn State's College of Agricultural Sciences contributed to the first complete genome sequence of a harmful plant pathogen from an ornamental Prunus host through an active-learning activity in a plant ...
Scientists know a great deal about how lions hunt, breed and survive, but the microscopic communities living inside them have remained largely unexplored. Now, a study of wild lions in Namibia is beginning to change that, ...
A Université de Montréal–led research team has analyzed the genetic origins of human remains found in Old Montreal—and uncovered unexpected results.
Changes in our genes affect health risks from heart disease to cancer, but how those genes are turned on and off is just as crucial to health. What's more, almost all genes occur as two copies—one from each parent—that aren't ...
Researchers at the University of Miami have identified a group of previously unknown viruses that bridge an evolutionary gap between viruses and cellular protein compartments, a discovery with implications for both biotechnology ...
Bacteriophages, or viruses that infect bacteria, have a fiendishly simple purpose in life: attach to a bacterial cell, inject their DNA and then use the host's genetic machinery to reproduce. In doing so, they may have evolved ...
Somatic mutations, the DNA changes that occur as our bodies grow and age, not only hold an important key to cancer but are emerging as the seeds of a wide range of common, noncancerous diseases. The Somatic Mosaicism across ...
