Chronocyte hypothesis

WebFeb 7, 2002 · Hartman and Fedorov used their results to test the hypothesis that the nucleus was formed from the endosymbiosis of an archeon and a bacterium inside a third cell called a 'chronocyte'. Their analysis predicts that the chronocyte was an RNA-based cell that engulfed prokaryotic cells. This hypothesis is supported by the nature of the … Webchronocyte hypothesis evolved cytoskeleton and ability to eat other microbes by phagocytosis (so chronocyte ate archaean that resisted digestion --> eventually became endosymbiont--> organelle (the nucleus) this combo then spawned the eukarya then gained mitochondrion & chloroplast in same way 3 viruses, 3 domains hypothesis
