Elena L [17]

Answer:

The DNA is more closer to bacteria.

Explanation:

Mitochondria and chloroplast are considered as semi-autonomous organelle because they contain their own genetic material. The mitochondria and chloroplast evolution can be explained by the endosymbiont theory.

The DNA of mitochondria and chloroplast are more closely related to bacterial chromosome rather than eukaryotic chromosome.  Both the organelle and bacterial DNA are double stranded and  their translation can be inhibited by the chloramphenicol. Some of their replicating enzymes also show similar characteristics.

Thus, the DNA is more closer to bacteria.
