Central dogma

  1. 1. CENTRAL DOGMATo supplement the guided notes packet
  2. 2. The flow of genetic informationfrom DNA to RNA to proteinInitially, the central dogma of biology was simply thoughtof as DNA  mRNA protein
  3. 3. However, that has beenexpanded… Proteins can ‘force’ other transcription translation proteins to mimic themselves. Ex: Prion DiseasesDNA RNA Protein Environmen RNA can be autocatalytic (cut it self up) Reverse transcriptionBlue words = initial / classic understandingOrange words = new understandings
  4. 4. What do all those nitrogenousbases mean? On the RNA strand, each bracket contains 3 nucleotides. 3 nucleotides are called a codon, each codon represents an amino acid. There are 64 (43) possible code words which is more than enough to code for the 20 amino acids
  5. 5. Now it’s your turn.. You should be able to use the notes you took for homework to complete the questions up through the elongation stage of translation. Remember: There are lots of resources on the blog to help you!
