  1. a two identical copies of the cell's genetic information
  2. b an alteration in a sequence of DNA
    -change the normal message carried by the gene, causing a defect
    - they are random
    -affect the synthesis of proteins, which causes malfunctions in the cell. EX.) sickle cell anemia is caused by a substitution in the cell
    -can cause cell death
