The flashcards below were created by user Jess on FreezingBlue Flashcards. What would you like to do?


  1. Transcription in 3 steps
    • Initiation
    • Elongation
    • Termination
  2. Initiation
    mRNA and ribosomes come together at start codon.
  3. Elongation
    NTPs are added in the 5' to 3' direction.
  4. Termination
    • Self termination with a stem loop
    • Enzyme dependent
  5. Translation
    • Initiation
    • Elongation
    • Termination
  6. Initiation
    • mRNA and ribosomes come together
    • Starts at the P site with the AUG start codon
    • First amino acid is methionine
  7. Elongation
    • Add amino acids and form a peptide bond
    • Ribosome moves down the mRNA to the next codon
  8. Termination
    • Ribosome reaches the stop codon (UAA,UAG, and UGA)
    • Causes them all to come apart
