DNA Mutation 13:28 Mutation –  heritable change in genetic material [DNA for all cells on planet, but RNA for  viruses], changes are able to be copied – RNA/DNA polymerase can copy, changes in  nucleotide sequence   passed down to daughter cells; other changes can happen in  DNA [bend, condensed, etc] in what sense is damage to skin passed down [when cells  divide, daughter cells have same change in nucleotide sequence] not limited to  generation to generation necessarily, also cells to cells Point mutations from the DNA perspective  –  be able to recognize/be able to describe  what happened to DNA point mutation  – small mutation, affects 1 nucleotide [directly] or 1 base pair  we have 6 billion base pairs of DNA, nothing happens until replication [base pair –  indirectly – usually see reflected in both strands] substitution  – changes the identity of the nucleotide/base pair but does not change the
