Choose the incorrect about mitochondria -

A

Has 80S ribosome

B

Naked circular DNA

C

ETS on inner mitochondrial membrane

D

Power house of the cell

Correct Answer

Option A

Detailed Explanation

The correct answer is A) Has 80S ribosome because mitochondria actually contain 70S ribosomes, which are more similar to those found in prokaryotes. The presence of 80S ribosomes is characteristic of eukaryotic cytoplasm, not mitochondria. This distinction highlights the semi-autonomous nature of mitochondria, which possess their own DNA and ribosomes, resembling those of bacteria.
