Question 7
--/1
Two populations of bacteria, Bacteria A and Bacteria B, each develop a resistance to an antibiotic. The
resistance genes seem to originate from an R plasmid. Bacteria A only contains the R plasmid. Bacteria B
contains the R plasmid as well as an F plasmid, allowing conjugation.
If we were introduce bacteria B into the bacteria A population, how would you expect the movement of the
resistance gene to change?
Bacteria B could transfer the F plasmid into the bacteria A population, causing an
increase in resistance in bacteria A.
Not enough information to tell.
There is no reason to think they would change at all.
It would slow down the developement of antibiotic resistance for both populations.
