Cellular division strategy shared across all domains of life

(Harvard John A. Paulson School of Engineering and Applied Sciences) The three domains of life -- archaea, bacteria, and eukarya -- may have more in common than previously thought. Over the past several years, Harvard researchers have been studying how cells regulate size. In previous studies, researchers found that E. coli (bacteria) and budding yeast (eukaryote) use the same cellular mechanisms to ensure uniform cell sizes within a population. Now, the team found that archaea use the very same...
