Mutations
Mutations

  • Some are positive

  • Some are negative

  • Some have no effect

    • Amino acids have multiple codons

  • Pick a number 1-10…

  • Mutagen= Chemical or physical agent that causes a mutation

  • ?

    Mutations1
    Mutations

    • 2 different types of mutations

    • Gene mutations

      • Changes at the base level

    • Chromosomal mutations

      • Changes in the number or structure of chromosomes


    Gene mutations
    Gene Mutations

    1. Point mutation

    • Substitution

      • Changes in a single gene

      • CTC glutamic acid hydrophilic

      • A is substituted for T

      • CAC valine hydrophobic

      • Causes sickle cell disease
