\((A)\) semi autonomous organelles
\((B)\) formed by division of pre existing organelles and they contain \(DNA\) but lack protein synthesising machinery.
Which one of the following options is correct ?
- A \((A)\) is true but \((B)\) is false.
- B Both \((A)\) and \((B)\) are false.
- C Both \((A)\) and \((B)\) are correct.
