AIIMS 2018 Botany Biology MCQ Question
Choose the incorrect about mitochondria -
Has 80S ribosome
Naked circular DNA
ETS on inner mitochondrial membrane
Power house of the cell
Correct Answer
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.
