The Cell’s Protein Factory: From DNA to Function 🧬 Every protein in your body starts as a message inside the nucleus. DNA is first copied into mRNA, which travels to ribosomes — the cell’s assembly line — to build a protein chain. The rough ER folds and checks the structure, while the Golgi apparatus packages it for delivery. Finally, vesicles transport the finished protein to where it’s needed, keeping cells working, repairing, and communicating every second. #ProteinSynthesis #CellBiology #Mo
