Latest Mobile genetic elements Stories
A Rice University undergraduate will depart with not only a degree but also a possible patent for his invention of an efficient way to create protein libraries, an important component of biomolecular research.
Many living organisms suffer from parasites, which use the hosts’ resources for their own purposes. The problem of parasitism occurs at all levels right down to the DNA scale.
A team of geneticists and computational biologists in the UK today reveal how an ancient mechanism is involved in gene control and continues to drive genome evolution.
Small, mobile sequences of DNA left over from viruses, called transposons or "jumping genes" because of their ability to move around the genome, pose a significant threat to the genetic integrity and stability of an organism.
For years, scientists believed the vast phenotypic differences between humans and chimpanzees would be easily explained – the two species must have significantly different genetic makeups.
Genetic parasites invaded the mammalian genome more than 100 million years ago and dramatically changed the way mammals reproduce -- transforming the uterus in the ancestors of humans and other mammals from the production of eggs to a nurturing home for developing young.
A team at the Stanford University School of Medicine has cataloged, down to the letter, exactly what parts of the genetic code are essential for survival in one bacterial species, Caulobacter crescentus.
For more than a decade, Dr. Susan Rosenberg, professor of molecular and human genetics at Baylor College of Medicine, has solidified her premise that when cells are under stress, the rate of gene changes called mutations goes up, a finding that has implications for a wide variety of biological phenomena â€“ from evolution to antibiotic resistance and cancer.
Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have developed a new method for studying gene regulation, by employing a jumping gene as an informant.
The Massachusetts General Hospital (MGH) research team that first discovered tumor-associated RNA in tiny membrane-enclosed sacs released into the bloodstream by cancer cells has now found that these microvesicles also contain segments of tumor DNA, including retrotransposons â€“ also called "jumping genes" â€“ that copy and insert themselves into other areas of the genome.
