Question
Transcribed Image Text:A Toxoplasma gondii mutant (shown below) was made by Hunter and
Sibley. The mutant T. gondii had a truncated ROP18 gene which prevented
ROP 18 from binding to the parasitophorous vacuole as shown in the figure
below. What would you expect to see when a host mouse was infected with
this mutant T. gondii?
