Boffins Develop New Technique to Hunt Illness-causing Mutants in Non-gene DNA
University of Utah geneticists say that they have developed a faster, less expensive technique to hunt illness-causing mutants in large, non-gene stretches of DNA. The development of the new technique is important because diseases can result not only from mutant genes, but also from mutations of o...Striking a Gold Mine: H5N1 Vaccine may Serve as an Antidote for Mutants and Variants
