Polypeptide chains (protein) are made on the?Golgi apparatus lysosome smooth endoplasmic reticulum rough endoplasmic reticulum

A
polypeptide is a long chain of amino acids. These are produced on the ribosomes, during protein
synthesis. Messenger RNA contains the genetic code to assemble the polypeptide. Transfer RNA
carries the appropriate amino acids to the growing polypeptide chain. Eventually, a stop message
is reached. The polypeptide detaches from the ribosome and proceeds to fold into a three
dimensional protein. This process occurs along a ribosome. Some of these are found in the
cytoplasm and others are located along the endoplasmic reticulum. The rough endoplasmic
reticulum contains many ribosomes. Thus, the answer to the question is choice
