Best Answer: Protist are eukaryotic, meaning they have a nucleus and membrane bound DNA complexes. Bacteria are prokaryotes without membrane bound DNA complexes or organelles. Bacteria carry their DNA in one long strand within the cells cytoplasm.They are each actually in different kingdoms the highest form of classification. Protista and Monera (bacteria's kingdom).Other kingdoms are Plant, Animal, and Fungi.acteria are prokaryotes without membrane bound DNA complexes or organelles.
