Question

where is dna stored in prokaryotic cells? all of these cytoplasm nucleus mitochondria

Explanation:

Prokaryotic cells, such as bacteria, lack a nucleus. Their DNA is not enclosed within a membrane - bound nucleus. Instead, the DNA is located in the cytoplasm. Prokaryotes do not have mitochondria (an organelle with its own DNA in eukaryotes). The first option "All of these" is incorrect because nucleus and mitochondria are not present in prokaryotes.

Answer:

Cytoplasm
