OVERVEIW OF THE PROCESS OF DNA BECOMING PROTEIN
1. 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
