Ribosomes

These small organelles form the machinery of the cell that makes synthesises protein, and are located on the ‘rough’ endoplasmic reticulum of eukaryotic cells.  They consist of proteins and ribosomal RNA (rRNA), and receive messenger RNA (mRNA) copied from DNA, as well as amino acids.  They translate the mRNA through using its coded instructions to assemble amino acids in a particular order.  In doing so, they make a strand of a particular protein.
