Answer:

C

Explanation:

Both mitochondria and chloroplasts have their own DNA that is different from the nuclear DNA of the larger host cell.

Mitochondrial DNA (mtDNA) and chloroplast DNA (cpDNA) actually more closely resemble the structure of prokaryotic DNA (circular) as compared to the structure of eukaryotic DNA (linear).

The endosymbiotic theory proposes that mitochondria and chloroplast were once independent prokaryotic organisms that survived endocytosis by an early eukaryotic cell.

  • The statement "both mitochondria and chloroplasts have their own DNA that is different from the nuclear DNA of the larger host cell"  helps support the endosymbiotic theory (Option C).

The lines of evidence that support the endosymbiotic theory include:

  • Both mitochondria and chloroplasts have their own circular DNA and divide by binary fission.

  • Both mitochondria and chloroplasts have their own bacteria-like ribosomes (70 S).

  • Both mitochondria and chloroplasts have a similar size as prokaryotic cells.

In conclusion, the statement "both mitochondria and chloroplasts have their own DNA that is different from the nuclear DNA of the larger host cell"  helps support the endosymbiotic theory (Option C).
