  3. POINT MUTATION Substitution- a change in a SINGLE BASE of DNA. ACG TA CCC T ISO DNA – mRNA – tRNA TAT – AUA – UAU ACG TA CCC A DNA – mRNA – tRNA TAA – AUU – UAA ISO

  4. FRAMESHIFT MUTATION A single base is added (insertion) or deleted (deletion) resulting in a shift of codon groups. THE DO BIT THE CAT G THE DO G B I T T H E C A T ACG AT CCC T DNA – mRNA – tRNA TAT – AUA – UAU ISO ACG T A T C C C DNA – mRNA – tRNA ATC – UAG – AUC STOP
