Solution

Ribosomes:

  1. The ribosome is a sophisticated molecule that cells use as a factory for synthesizing proteins. It is made up of proteins and ribosomal RNA molecules.
  2. A ribosome is made up of RNA and proteins.
  3. The small and big subunits of each ribosome are two distinct RNA-protein complexes
  4. Small subunit: The small RNA subunit which reads the RNA.
  5. Large subunit: Large subunit joins together the mRNA and the tRNA to form polypeptide chains.
  6. A cell's nucleus, mitochondria, and chloroplasts are the only places where DNA can be found.
  7. Thus, No ribosomes do not contain DNA.
