For example:  GGATACCTAGGTAAT

Insertion: GGAT<u>G</u>ACCTAGGTAAT

a nucleotide that was not present before is inserted into the original sequence

Substitution: <u>C</u>GATACCTAGGTAAT

the first nucleotide was substituted in for another (C for G)

Frameshift (basically a insertion or deletion, we'll try deletion here): GATACCTAGGTAAT

the first nucleotide was deleted, causing the reading frame to be shifted (instead of GGA as the first codon, we have GAT)
