CHAPTER 10 Bacterial Genetics

CHAPTER 10 Bacterial Genetics. Mutation and Recombination, Mutations and Mutants. Mutation is a heritable change in DNA sequence that can lead to a change in phenotype . By definition, a mutant differs from its parental strain in genotype , the nucleotide sequence of the genome.
