The correct answer is: These are composed of ribonucleic acid and proteins.
Ribosomes are amembraneous (i.e., without membrane) cell organelle composed of rRNA and protein. These are found in both prokaryotic and eukaryotic cells. In prokaryotes, ribosomes are 70S type while in eukaryotes, it is 80S type. Here ‘S’ (Svedberg’s Unit) stands for the sedimentation coefficient.
