The bacterium Escherichia coli (or E. coli) is a single-celled organism that lives in the gut of healthy humans and animals. Its body shape can be modeled as a 2-μm-long cylinder with a 1 µm diameter, and it has a mass of 1 x 10-12 Its chromosome consists of a single doublestranded chain of DNA 700 times longer than its body length. The bacterium moves at a constant speed of 20 µm/s, though not always in the same direction. Answer the following questions about E. coli using Sl units (unless specifically requested otherwise) and correct significant figures. a. What is its length?
