  1. Plasmid carrying a gene for antibiotic resistance Individual bacteria cells Sex pilus Antibiotic resistance increases with time and becomes an established characteristic in the population.

  2. Round 3 introduced an antibiotic. Students who lacked the antibiotic-resistance gene on the yellow plasmid had to sit out this round because they did not survive exposure to the antibiotic. Having more yellow circles gives them more copies of the resistance gene, and may help them resist additional exposure to the antibiotic. Only by taking the full course can you be sure of killing all the bacteria in your system that caused you to become sick in the first place; if any of those bacteria remain, your infection could return. In addition, by not killing them, you've given them more time to reproduce, increasing the possibility that they may acquire resistance either from random mutations or from other bacteria in your system and become tougher to fight off next time you're sick.
