Biologists Construct a “Periodic Table” for Cell Nuclei – And Discover Something Strange, Baffling and Unexpected By Baylor College of Medicine on May 29, 2021 In a paper published in Science, biologists at Baylor College of Medicine, the Netherlands Cancer Institute and Rice University studying the tree of life unveil a new classification system for cell nuclei and the discovery of a method for transmuting one type of cell nucleus into another.

This week, a team of biologists studying the tree of life has unveiled a new classification system for cell nuclei, and discovered a method for transmuting one type of cell nucleus into another. The study, which appears this week in the journal Science, emerged from several once-separate efforts. One centered on the DNA Zoo, an international consortium spanning dozens of institutions including Baylor College of Medicine, the National Science Foundation-supported Center for Theoretical Biological Physics (CTBP) at Rice University, the University of Western Australia and SeaWorld. Scientists on the DNA Zoo team had been working together to classify how chromosomes — which can be several meters long — fold up to fit inside the nuclei of different species from across the tree of life. “Whether we were looking at worms or urchins, sea squirts or coral, we kept seeing the same folding patterns coming up,” said Olga Dudchenko, co-first author of the new study and a member of The Center for Genome Architecture at Baylor and CTBP. #subsribeouryoutubechannel #ChemDude035 #likesharecomment #followformore #learn #Chemistry #Chemistryposts #Chemistryjokes #Latestnews #aboutchemistry #trending #Chemistryknowledge #MDCAT #ECAT #MCAT #GK #GKpreperation #JobMCQs #ChemistryMCQs #MCQs #Biology #BiologicalPeriodictable #Invention #Periodictableforbiologists (at Peaceful Pakistan) https://www.instagram.com/p/CPgL8srJ1Zn/?utm_medium=tumblr
