1. The code to make a particular protein lies on a DNA molecule in the nucleus
2. mRNA copies the code from the DNA (transcription) with the assistance of RNA polymerase (enzyme)
3. mRNA leaves the nucleus through a nuclear pore towards the cytoplasm to a ribosome
4. Ribosomes will assemble the protein from the amino acids
5. tRNA will collect all the amino acids from the cytoplasm to match the amino acids brought by mRNA (translation)
6. Line up all the amino acids forming a polypeptide chain
