Explanation:
Detailed explanation-1: -The endoplasmic reticulum (ER). (A) Electron micrograph of rough ER in rat liver cells. Ribosomes are attached to the cytosolic face of the ER membrane.
Detailed explanation-2: -Ribosomes bind to messenger RNAs and use their sequences for determining the correct sequence of amino acids to generate a given protein.
Detailed explanation-3: -Once the protein backbone amino acids are polymerized, the ribosome releases the protein and it is transported to the cytoplasm in prokaryotes or to the Golgi apparatus in eukaryotes. There, the proteins are completed and released inside or outside the cell.
