The correct option is D A- Ribosome, B- Nucleoid
A- Ribosomes
Both prokaryotes and eukaryotes have ribosomes. Ribosomes are organelles found attached to the RER or freely floating in the cytoplasm of living cells. These organelles are involved in the protein synthesis.
B- Nucleiod
Unlike eukaryotes, prokaryotes do not have a membrane enclosed nucleus. Their genetic material is contained in a region called the nucleoid.
