Question

What are found in both mitochondria and typical prokaryotic cells?

80S ribosomes and circular DNA
70S ribosomes and circular DNA
70S ribosomes only
circular DNA only

Answer 1

B) 70S ribosomes and circular DNA

Step-by-step explanation:

Remember: Mitochondria is found in the cytoplasm of almost all eukaryotic cells.

All prokaryotes have 70S ribosomes. Eukaryotes have 80S ribosomes, with some exceptions like mitochondria and chloroplast.

Circular DNA is DNA that forms a closed loop and carries genetic material. In both prokaryotes and eukaryotes, the chromosome represents circular DNA, although in eukaryotes, the chromosomes are more complex in structure.
