Mutation - Heritable change in DNA sequence that can lead to a change in phenotype Phenotype - observable properties of an organism Mutant - a strain of any cell or virus differing from parental strain genotype Genotype - nucleotide sequence of genome Wild-type Strain - Typically refers to stain isolated from nature Selectable Mutations - -those that give the mutant a growth advantage under certain conditions -useful in genetic research
