Protein Synthesis A) Transcription (nucleus) 1. RNA polymerase separates DNA and assembles mRNA 2. mRNA leaves nucleus B) Translation (cytoplasm) 3. mRNA attaches to ribosome 4. tRNA , with an attached amino acid, comes to ribosome 5. ribosome binds the anticodon to the codon 6. new tRNA comes as ribosome moves along mRNA 7. ribosome helps form a peptide bond between the amino acids 8. polypeptide chain is formed
