3. Transcription & Translation

4. Transcription DNA is used to make a single strand of RNA that is complementary to the DNA base pairs. The enzyme used is RNA polymerase

6. Translation Protein being made from the RNA template RNA messenger= carries message from DNA Ribosomal RNA= ribosome that reads the mRNA Transfer RNA= transfers the amino acid from the code of nitrogen bases

7. Steps of Translation 1. mRNA finds a ribosome 2. mRNA is read by the ribosome 3. Every 3 bases = codon 4. Each codon read = 1 amino acid brought by the tRNA (3 bases on anticodon) 5. Many amino acids strung together = polypeptide = protein

8. Translation Initiation- Small ribosome subunit finds bases AUG, then the large subunit binds and starts the process Elongation- Amino acids are bonded by peptide bonds Termination- Stop codon (UAA, UAG, or UGA) signals the release of the polypeptide from the ribosome
