Vedclass · Answer

(B) The endosymbiont hypothesis proposes that mitochondria and chloroplasts originated from free-living prokaryotes that were engulfed by a host cell.Key similarities supporting this include:$1$. Both mitochondria and chloroplasts contain circular $DNA$,which is similar to the bacterial genome.$2$. This $DNA$ is not associated with histone proteins,a characteristic feature of prokaryotic $DNA$.$3$. They possess $70S$ ribosomes,which are characteristic of prokaryotes,rather than the $80S$ ribosomes found in the eukaryotic cytoplasm.
