DNA is contained in the nucleus of eukaryotes (plants/animals) 2. DNA mRNA The DNA message gets copied into mRNA. This is called transcription. 3. The mRNA leaves nucleus and sticks to ribosomes. (The ribosomes can be floating in cytoplasm (free) or stuck to rough endoplasmic reticulum.) 4. Ribosome moves along mRNA and provides enzymes (the keys to make it work) necessary for translation tRNA carries amino acids into place onto matching mRNA codon. 5. Amino acids stick together with many polypeptide bonds. 6. Amino acid chain undergoes processing and folding to become final protein INSIDE THE NUCLEUS Key to Colors ___________ T= ________ G = _____ C= ________ U= ___________H =__________ DR = Deoxyribose P = Phosphate A= Adenine bonds with____________ Cytosine bonds with____________ Gamine bonds with_____________ There is no ______________in DNA 1.
