It shows a radioautograph of an intact E. coli chromosome in the act of replicating. From this image, Cairns conclud... Read More
The common waterborne bacterium Caulobacter crescentus reproduces asymmetrically. When a cell divides, one of its daughter cells is a free-swimming “swarmer,” powered by a hairlike flagellum. The other, “stalk” daughter cell is immobile, anchoring itself to a surface with one of nature’s stronge... Read More
