Textbook Question
Chapter 1, Problem 60GP
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 SI units (unless specifically requested otherwise) and correct significant figures.
- a. What is its length?
- b. Diameter?
- c. Mass?
- d. What is the length of its DNA, in millimeters?
- e. If the organism were to move along a straight path, how many meters would it travel in one day?
