Presentation Transcript

  1. TRANSLATION NOTES

  2. How to crack the code… 3 digit code (triplets) “3 letter words that code for amino acids”

  3. Base Pairing mRNA – codon tRNA – anticodon mRNA AUG CCU CAU AUC AUU tRNA UAC GGA GUA UAG UAA

  4. tRNA Structure

  5. Amino Acid Codon Chart

  6. mRNA AUG CCU CAU AUC UAA tRNA UAC GGA GUA UAG AUU Amino Acid Met Pro His Iso stop

  7. 3 Steps of Translationmaking proteins1. Initiation2. Elongation3. Termination

  8. Step 1: Initiation • Ribosome attaches to the mRNA • b) Start codon is always AUG

  9. Step 2: Elongation a) tRNA anticodon matches with codon on mRNA b) Peptide bonds are formed between the amino acids

  10. Elongation (continued) c) A.A. released from tRNA d) Ribosome moves down the mRNA and continues adding A.A.

  11. Step 3: Termination • The ribosome reaches one of three stop • codons (UAA, UAG, UGA) • b) The mRNA and protein (polypeptide chain) • released
