1. Transcription Protein Synthesis Part 1 pp. 204-206

2. Overview  The first step to making proteins is called transcription  DNA  RNA  Protein

3. Location  Prokaryote: Cytoplasm  Eukaryote: Nucleus

4. Transcription  DNA  RNA  Protein  DNA is “rewritten” into mRNA  Only genes needed for specific proteins are transcribed

5. Transcription  RNA Polymerase binds to DNA  DNA unzips

6. Transcription  RNA Polymerase adds complementary RNA Nucleotides  RNA has Uracil (U) instead of Thymine (T)  Guanine and Thymine are the same

7. Transcription  EXAMPLE:  Polymerase falls off & DNA rebinds DNA Strand T C A G C A G C T A G T A G T C G T C G A T C A mRNA Strand A G U C G U C G A U C A

8. Result of Transcription  Produces a single strand of RNA  mRNA then carries “instructions” to ribosomes in the cytoplasm to make proteins

9. Vocabulary  Transcription  Uracil  RNA Polymerase  In your tables, summarize the main goal of Transcription
