118 Protein Synthesis Summary Nucleus Cytoplasm The diagram above shows an overview of the process of protein synthesis. It is a combination of the diagrams from the previous two pages. Each of the major steps in the process are numbered, while structures are labelled with letters. 1. Briefly describe each of the numbered processes in the diagram above: (a) Process 1: TRANSCRIPTION OCCURS. DNA STRAND SPLIT AND (b) Process 2: The mRNA leaves the nucleus and travels to ribosome (c) Process 3: The mRNA code decides which amino acid can connect (d) Process 4: Translation occurs. (e) Process 5: Amino acids arrange in the correct order on the ribosome (f) Process 6: Peptide bonds are made by forming peptide bonds (g) Process 7: protein chain is done (h) Process 8: protein has been released and is now free in the cell 2. Identify each of the structures marked with a letter and write their names below in the spaces provided: (a) Structure A: (b) Structure B: (c) Structure C: (d) Structure D: (e) Structure E: (f) Structure F: (g) Structure G: (h) Structure H: (i) Structure I: (j) Structure J: 3. Describe two factors that would determine whether or not a particular protein is produced in the cell: (a) (b)
