The process described is called protein synthesis, also called translation, it is a process in which the information contained in a messenger RNA molecule is converted into proteins.

The process of protein synthesis, also called translation, is based on the reading of messenger RNA and the union of amino acids corresponding to the codon sequence (sequence of three nitrogenous bases) present in this RNA. In protein synthesis, therefore, the conversion of information contained in RNA molecules into proteins occurs.

The endoplasmic reticulum, Golgi apparatus and lysosomes are part of the endomembrane system.

The ER signal sequence is a hydrophobic aminoacidic region of the protein located at the N-terminal end which is recognized by the signal-recognition particle (SRP) and its receptor located on the rough endoplasmic reticulum membrane.

Therefore, proteins destined for the ER are translated by cytosolic ribosomes and are targeted to the ER when a signal sequence emerges during translation.
