An experiment that exposed E. coli to the T1 bacteriophage proved that selection did not give rise to these entities; that experiment was named for Luria and Delbruck.

Salmonella typhimurium is exposed to histidine-free environments to measure a substance's ability to cause these in the Ames test. Wobble base pairing can prevent some of these from resulting in changes in amino acid sequences. Insertion or deletion of nucleotides may cause the "frameshift" type, while sickle-cell anemia results from the "point" type. Carcinogens are particularly potent at causing these. For 10 points, name these changes that occur in the nucleotide sequence of a genome.
