Respuesta :
The correct answer would be option D.
Ribosomal RNA or ribosomes are the site if protein synthesis in a cell.
The small and large subunits of the ribosome form a complex around the initiation codon of mRNA.
The ribosome also has a peptidyl transferase activity which helps in adding amino acid to growing polypeptide chain.
Thus, in absence of ribosome no polypeptide chain would form.
