Researchers have found new evidence of advanced DNA regulation in an ancient marine organism that shows crucial mechanisms turning genes on and off may have originated much earlier than thought, a discovery that points to a better understanding of genetic processes and disease treatment. The study, co-led by Australian researchers, analysed the DNA of Amphioxus and uncovered the tricks used to control gene expression, which may have originated much earlier than thought, Xinhua news agency quoted a statement by Garvan Institute of Medical Research in Australia. The translucent fish-like organism lay right at the vertebrate-invertebrate boundary and was perfectly positioned to
