Numbers

- Most cells are microscopic, yet most human cells have over 3,000,000,000 base pairs (in the right order) packed inside them.

- The average human body has trillions of red blood cells (1,000,000,000,000), and produced 2,000,000 new ones per second.

- e. coli can replicate themselves every 20 minutes. One bacterium can thus yield eight in one hour, or, in theory, 4 thousand billion billion bacteria in a day.

Biology is awesome.
