Which of the following is not a characteristic of mitochondria?
Options
- APossess single circular ds DNA
- BContain 80 S ribosome
- CHave their own specific enzymes
- DProduce new mitochondria
Correct answer
B. Contain 80 S ribosome
Step-by-step solution
Mitochondria possess their own circular DNA (mtDNA) which can replicate independently. mIDNA can produce its own m RNA and protein and some of the enzymes required for functioning. They can produce new mitochondria by division or binary fission from pre-existing mitochondria. Mitochondria also have their own ribosomes but they are of 70 S type like that of prokaryotes.
