91
New cards
Starting from the DNA inside of the nucleus, trace a path to create a protein and ship it out of the cell
1. DNA inside of the nucleus has instructions to make proteins
2. In the nucleus DNA is copied to MRNA
3. MRNA leaves the nucleus to the ribosomes on the rough ER
4. Ribosomes at rough ER moves the protein
5. protein moves through smooth ER
6. protein moves to golgi: golgi sorts, modifies, and packages the protein
7. the protein moves out of the cell by active transport (specifically exocytosis)
