The mitochondria of eukaryotic cells and bacteria share which of the following features?

• A. Cell wall composed of peptidoglycan
• B. Linear chromosomes
• C. Presence of circular DNA
• D. Ability to perform photosynthesis

Answer: (C)

Verified step by step guidance

1. Step 1: Understand the question is asking about shared features between mitochondria of eukaryotic cells and bacteria, focusing on structural or genetic characteristics.
2. Step 2: Recall that mitochondria and bacteria both have circular DNA, which is distinct from the linear chromosomes found in the nuclei of eukaryotic cells.
3. Step 3: Recognize that mitochondria do not have a cell wall composed of peptidoglycan; this is a feature specific to bacterial cell walls.
4. Step 4: Note that mitochondria do not perform photosynthesis; this function is typical of chloroplasts in plant cells and some bacteria.
5. Step 5: Conclude that the shared feature is the presence of circular DNA, reflecting the evolutionary origin of mitochondria from ancestral bacteria.
