Final answer:
Translation occurs in ER ribosomes during protein synthesis. The ribosome reads mRNA and assembles amino acids into a polypeptide chain according to the genetic code. This process is important for the production of secreted or membrane-bound proteins.
Step-by-step explanation:
Translation occurs in the ER ribosomes during the process of protein synthesis. During translation, the ribosome reads the mRNA sequence and assembles amino acids into a polypeptide chain according to the genetic code. This process involves the binding of charged tRNAs to the mRNA and the formation of peptide bonds between adjacent amino acids. Translation in the ER ribosomes is important for the production of proteins that are intended for secretion or insertion into the cell membrane.
