The Biological Overview Effect,Before we look at the biochemical machinery that enables cells to count molecules, to compare counts made at different times, and to use these results to control the direction of flagellar rotation, we need to know more about cell architecture.

Constrain

Flagellar Motion,Whether a cell runs or tumbles depends on the direction of rotation of its flagella, but the story turns out to be rather complicated. A tumble involves not only a change in the direction of rotation of one or more of the flagellar filaments, but also a sequence of changes in their handedness and pitch.

But the single-lens instruments that he made himself had fewer aberrations than the compound instruments of his day, so he was able to see more. And his curiosity was insatiable. His work on little animals—he called them animalcules—is available to the mode

A cell swims steadily in one direction for a second or so (in a direction roughly parallel to its body axis), moves erratically for a small fraction of a second, and then swims steadily again in a different direction. Some cells wobble from side to side or tumble end ove
