On December 19, 1979, Japanese scholars first identified the genetic structure of cancer-causing adenovirus in the world. In December 1979, a team of researchers from the University of Tokyo Medical Sciences Institute and Sapporo Cancer Institute identified the entire structure of the ¡°cancer-causing genes¡± of the 12 types of adenovirus that cause cancer in animal cells. In December 1979, a group of researchers from the University of Tokyo Medical Sciences Institute and Sapporo Cancer Research Institute identified the entire structure of the ¡°cancer-causing genes¡± of the 12 types of adenovirus that cause cancer in animal cells. This study that the genetic structure of the cancer-causing gene was composed of two thousand and thirty-two algae in a certain order, which coded the two unknown specific proteins of the cancer-causing
