The experiment is now at generation 68,113 (approximately). The bacteria have been maintained in the same medium—the same environment—over the course of the experiment.

For example, in a 20-generation experiment, a mutation occurring at the 10th generation of bacteria would give 1,024 phage-resistant variants. A mutation occurring at the 17th generation would ...

In the LTEE, however, where every generation of bacteria is introduced to the same set of conditions as its ancestors, there is no variability. And when they grow through more than six generations ...

For example, in a 20-generation experiment, a mutation occurring at the 10th generation of bacteria would give 1,024 phage-resistant variants.

If we can work out the roles plasmids play inside bacteria, then we can use the information to develop a new generation of ...

How the Experiment Worked. Luria's setup involved several tubes and dishes. Each tube contained a nutrient broth for the ...

The experiments designed to create resistant bacteria found that very few cells can withstand treatment. This means they are less likely to pass on their advantages to the next generation of bacteria.
