…at the root of cell formation. They found that DNA executes an unexpected architectural role in shaping the cells of bacteria. Studying the bacterium Bacillus subtilis, the researchers used an array of experiments and technologies to reveal that DNA, beyond serving to encode genetic information, also “pumps up” bacterial cells.

…code. Yet different types of cells read the same DNA in widely different ways, influenced by chemical chemical tags that modify the genetic material without changing the underlying DNA sequence. Scientists today announced significant progress in the unraveling of the code that guides those differences, a body of information they…
