Which of the following contains its own DNA and ribosomes?Group of answer choicesvacuolelysosomeperoxisomeGolgi apparatusmitochondrion

To determine which of the listed organelles contains its own DNA and ribosomes, let’s analyze each option:

1. Vacuole: Generally does not contain DNA or ribosomes. Vacuoles are primarily used for storage and maintenance of cell turgor.

2. Lysosome: These organelles contain enzymes for digestion but do not have their own DNA or ribosomes.

3. Peroxisome: Peroxisomes are involved in fatty acid metabolism and detoxification and also lack their own DNA and ribosomes.

4. Golgi apparatus: This organelle modifies, sorts, and packages proteins and lipids, but it does not have its own DNA or ribosomes.

5. Mitochondrion: This organelle is known as the powerhouse of the cell and is unique because it contains its own DNA (circular DNA similar to that of bacteria) and ribosomes (70S ribosomes).

Final Answer

The correct choice is mitochondrion, as it contains its own DNA and ribosomes.
