So how does one cell become 37.2 trillion cells? Through mitosis. Mitosis is the process of cell division, in which one cell produces two new daughter cells that are genetically identical to … Continue reading Mitosis

Just a week ago, a discussion flared up on Reddit about the consequences for everything from creating human brain-less organ farms to custom babies. The study will really only benefit basic sciences and advanced biotechnology, where people use … Continue reading Genetically modified yeast and Science Fiction
