ribosome
Cellular translation machinery
A ribosome is a tiny cellular structure that assembles proteins by reading genetic instructions from messenger RNA.
Ribosomes occur in all living cells, either floating freely in the cytoplasm or attached to the endoplasmic reticulum.
They're composed of RNA and proteins, working as molecular machines that translate genetic code into the amino acid chains that become proteins.
