- Role of the Golgi Apparatus
- Step 1
- Transcription of DNA to mRNA
- Step 2
- mRNA leaves nucleus
- Step 3
- Protein made on ribosomes enter ER
- Step 4
- Protein moves through the ER assuming three-dimensional shape en route
- Step 5
- Vesicles pinched off the rER contain the protein
- Step 6
- Vesicles from the rER fuse to form the flattened sacs of the Golgi apparatus
- Step 7
- Proteins are modified within the Golgi apparatus
- Step 8
- Vesicles pinched off the Golgi apparatus contain the modified protein
- Step 9
- Vesicle fuses with cell surface membrane releasing protein, such as extracellular enzymes
- Step 1
