Latest Paramutation Stories
U.S. scientists say they have proposed a definition of epigenetics -- a new research field focusing on heritable genetic alterations not caused by DNA. Ali Shilatifard of the Stowers Institute for Medical Research met with colleagues in December at the Cold Spring Harbor Laboratory in New York to develop a consensus definition of epigenetic traits for consideration by the broader research community. Shilatifard said the definition is intended to address confusion within the scientific...
A newly cloned gene in corn will help explain how unusual interactions between a parent's genes can have lasting effects in future generations. The finding has implications for breeding better crop plants and unraveling complex genetic diseases. The new research indicates that an additional molecule, DNA's little cousin RNA, is needed for the intriguing gene interactions known as paramutation.Paramutation doesn't follow the laws of classical Mendelian genetics. "Paramutation is this...
