Q: Which of the following organelles can replicate itself ?
  • A. Cytoplasm
  • B. Vacuole
  • C. Golgi apparatus
  • D. Mitochondrion
Correct Answer: Option D - The organelle that is capable of replicating itself is mitochondrion. Mitochondrion have their own set of DNA replication machinery, which is distinct from the cell's nuclear DNA replication system. This machinery includes unique enzymes and factors. The mitochondrial DNA is a circular molecule, and during replication, a structure known as the D-looP is formed.
