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

Properties of all cells - growth, metabolism, and evolution. growth - multiply within hours metabolism - capture light energy by doing enzymatic reactions evolution - changes in their DNA that encodes differences that change over time. LUCA - Last Universal Common Ancestor prokaryote - before the nucleus eukaryote - after the nucleu
