A) Describe in detail how Streptococcus pneumoniae has developed antibiotic resistance over the past century.
Streptococcus pneumonia has developed resistance over time against antibiotics and over drugs. Those bacteria that remain rapidly evolve and replicate leaving those that are susceptible to die out, and leaving the ones which are resistant to survive.
B) Start the clock. The one minute of division here represents 186 days of actual division. How many times did the cells divide in this time? How many total cells resulted at the end of this time? How many mutations occcurred in the population during this time?
Replicated 13,391 million times; population of 313, 753 million; 1,326 mutations
