Which cellular organelle contains RNA but not DNA?

Explanation:
Ribosome. This molecular machine is made of RNA and proteins and functions to translate mRNA into protein. Its RNA components (rRNA) form the catalytic centers and structural framework of the ribosome, but no DNA is housed inside the ribosome itself. DNA is stored in the nucleus, and in organelles like mitochondria and chloroplasts, which have their own DNA genomes. So the ribosome uniquely contains RNA without containing DNA.
