A drug that specifically inhibits the replication of the large DNA mass present in large mitochondria would be most effective at killing
A) euglenids.
B) ciliates.
C) Trypanosoma spp.
D) Toxoplasma spp.

Question

Quizplus · Accepted Answer

Trypanosoma spp. have large mitochondria with a single large DNA mass called kinetoplast, which is essential for their survival. Inhibiting the replication of this DNA mass would prevent the cell from producing enough energy and ultimately lead to the death of the parasite. This strategy would not be effective against euglenids and ciliates, which have smaller mitochondria, nor against Toxoplasma spp. which do not rely on mitochondrial DNA for energy production.
