  AMMONIA

  • NH3
  • high toxicity
  • 300-500 ml of H20 for excretion

  URIC ACID

  • N4H4C5H3
  • very low toxicity
  • .001 L

  UREA

  • N2H4CO
  • low toxicity
  • 50 mL
• Mutation

  Change in the DNA sequence of a gene
• Types of point mutations

  • Substitution of one base for another
  • Insertion or deletion of a single base pair
  • Inversion of two adjoining base pairs
• Missense mutation

  Changes a single amino acid in the coding sequence
• Nonsense mutation

  Results in a premature stop codon
• Silent mutation

  Does not alter the resulting sequence of amino acids
• Frameshift mutation

  Shift in the reading frame resulting in multiple missense/nonsense effects
• Types of large scale mutations

  • Involve multiple nucleotides
  • Involve entire genes
• Translocation


  Entire genes or groups of genes are moved from one chromosome to another
