WHY BACTERIA WITH IDENTICAL GENES DON’T ACT ALIKE

In a recent study, researchers showed that when a bacterial cell divides into two daughter cells there can be an uneven distribution of cellular organelles. The resulting cells can behave differently from each other, depending on which parts they received in the split.

“This is another way that cells within a population can diversify. Here we’ve shown it in a bacterium, but it probably is true for all cells, including human cells,” says Samuel Miller, professor of microbiology, genome sciences, and medicine at the University of Washington and the paper’s senior author.
