Proteins

1. Central Dogma

   • DNA->mRNA->Protein
   • Transcription
     • DNA->mRNA by RNA polymerase
   • Translaton
     • RNA->Protein
       • mRNA made in nucleus
         • goes to ribosome
           • protein synthesis in ribosome
             • Ribosome concidered an enzyme

2. made of amino acids

   • 3 base pairs of DNA = 1 Amino Acid
   • small proteins
     • 100 amino acids
   • large proteins
     • 1000-1500 amino acids

3. Proteosome

   • breaks down protein

4. affects protein folding

   • heat
   • light
   • pH
   • salt
   • detergent
